If the cursor is at the left end of the display no cursor movement is made. 6us Horizontal Tab 09H Moves the cursor right by one character. If the cursor is at the right end of the display the action depends on the write 6us (20us on scroll) mode currently selected. In DC1 and DC2 mode no cursor movement is made. In DC3 mode the entire contents of the display is scrolled left by one character, the right end character position is cleared. No cursor movement is made. Line Feed 0AH The display is cleared. No cursor movement is made. 6us (20us on scroll) Form Feed 0CH Moves the cursor to the left end. 6us Carriage Return 0DH Moves the cursor to the left end. 6us Clear 0EH Clear all displayed characters. No cursor movement is made. 65us Cancel 0FH Clear all displayed characters. No cursor movement is made. 65us Auto CR Mode (DC1) 11H Specifies automatic carriage return mode. (default) 6us Overwrite Mode (DC2) 12H Specifies character overwrite mode. 6us Horizontal Scroll Mode (DC3) 13H Specifies horizontal scroll mode. 6us Cursor Off (DC4) 14H The cursor is turned off 6us Cursor On (DC5) 15H The cursor is displayed as a blinking full block. The blink rate can be specified using the Blink Speed Control 6us command. Cursor Off (DC6) 16H The cursor is turned off 6us Cursor Off (DC7) 17H The cursor is turned off 6us International Font 18H All subsequent characters displayed will be from the International font. This font can also be selected as the default by 6us using the J6 hardware jumper link (OPEN). KATAKANA Font 19H All subsequent character displayed will be from the KATAKANA font. This font can also be selected as the default by 6us using the J6 hardware jumper link (LINKED). Euro Currency Mark 1AH This command enables the Euro currency mark at location ADH in the International font. Sending the International 6us Font command (or after a reset) restores the character at location ADH to a blank (this is the default condition). This will affect any existing ADH characters already on the display. User Defined Font 1BH Define a user character. Up to 16 user characters can be defined and stored by 6us (1BH) + 43H the module. The specified character code can be 00H – FFH. Command codes 4us (43H) Dot assignment + character code can be overwritten with a UDF so be aware that doing so will disable that 6us (byte 1) 6us (byte 2) + data byte 1 command. All UDF’s are lost on power off or reset. If more that 16 UDF’s are P1 P2 P3 P4 P5 6us (byte 3) + data byte 2 defined the older definitions are overwritten. 6us (byte 4) 15us (byte 5) + data byte 3 P6 P7 P8 P9 P10 Bit / Byte assignment + data byte 4 P11 P12 P13 P14 P15 + data byte 5 7 6 5 4 3 2 1 0 Byte 1 P8 P7 P6 P5 P4 P3 P2 P1 P16 P17 P18 P19 P20 Byte 2 P16 P15 P14 P13 P12 P11 P10 P9 P21 P22 P23 P24 P25 Byte 3 P24 P23 P22 P21 P20 P19 P18 P17 P26 P27 P28 P29 P30 Byte 4 P32 P31 P30 P29 P28 P27 P26 P25 P31 P32 P33 P34 P35 Byte 5 - - - - UL P35P34P33 UL Cursor Moving 1BH The cursor is moved to the specified position. The relationship between the position value and the display is as 6us (1BH) + 48H follows:- nd rd 4us (48H) Left end 2 col 3 col - Right end + position 4us (position) Top 00H 01H 02H - 13H Bottom 14H 15H 16H 27H Luminance 1BH The display luminance can be set to one of 4 levels. 6us (1BH) + 4CH luminance = 00H – 3FH specifies 25% 4us (4CH) + luminance luminance = 40H – 7FH specifies 50% 4us (luminance) luminance = 80H – BFH specifies 75% luminance = C0H – FFH specifies 100% (default) Flickerless Writing Mode 1BH Set flickerless write mode. By default, priority is given to data communication and display flicker can occur if data is 6us (1BH) + 53H sent to the display continuously. If flickerless writing mode is specified, priority is given to display refresh to avoid 6us (53H) possible flicker. Command and data busy times will be up to 200us longer when this mode is set. Blink Speed Control 1BH The blink rate of the cursor can be specified. Rate = speed x 30ms. (default=14H) 6us (1BH) + 54H 4us (54H) + speed 6us (speed) Initialise 1BH Clear the display, erase any defined characters, set the cursor position to the top left of the display and reset all 6us (1BH) + 49H settings to defaults. 40us (49H) Character Write 20H – FFH Display the specified character from the currently selected font (or UDF is defined) at the current cursor position. After 7us (20us on scroll) the character is written to the display a horizontal tab automatically follows. NORITAKE ITRON VFD MODULES CU20029-KTW220A Dot Graphic VFD Module CU20029-KTW220A PARALLEL COMMUNICATION Data on D0-D7 is clocked into the module when /CS is low and a rising edge is detected on /WR. The host must keep the data stable for the time period indicated in the timing diagram. The module busy line can be used to give a sufficient delay between commands. /CS >160nS >0nS I/O D0-D7 HOST CU20029-KTW220A /WR SYSTEM I/O BUSY >0nS >100nS >10nS I/O /CS GND VDD VDD GND D0 - D7 I/O Data Valid /WR <200nS tBUSY >2uS BUSY Parallel Interface Timing.
