After power on, it is necessary to reset./RESET is kept L between 5 clocks up(oscillation clock). b. When /HALT=L, the oscillation stops. The power supply for the LCD must now be turned off, to protect the LCD from DC bias. c. The HALT function includes the RESET function. d. The column/line counter and display register are cleared by RESET. (Other registers are not cleared.) Disable the display using the clear-display register. e. The status must be checked at the data or commands are sent. The MSB=0 status check must be done in particular. There is a possibility of erroneous operation due to a hard interrupt. f. STA0 and STA1 must be checked at the same time. When a command is executed, data transmission errors may occur. g. The T6963C can only handle one byte per machine cycle(16 clocks). It is impossible to send more than two data in a machine cycle. h. When using a command with operand data, it important to send the data first, and then execute the command. i. The character codes used by the T6963C are different from ASC codes. j.

The relationship between number of row/column and oscillation clock The frequency of the crystal oscillation is adjusted by the following formula. fOSC: Frequency of oscillation fSCP: Frequency of shift clock(fSCP=fOSC/2) WWW.SUNMAN.COM.CN 2010-3 2/23 Changsha Sunman Electronics Co., Ltd SMG240128A fR : Frequency of Frame M : Number if characters on one line(number of dots on one line=8M) For all font sizes(e.g.7X8,6X8,5X8) the oscillation frequency remains constant.

RAM Interface The external RAM is used to store display data(text, graphic and external CG data). With single-scan, text data, graphic data and external CG data can be freely allocated to the memory area(64 KB max). With dual-scan, LCD is allocated to 0000H to 7FFFH(32 KB max), LCD is allocated to 8000H to FFFFH(32 KB max). Text data, graphic data and external CG data can be freely allocated in LCD . In LCD , the same address must be allocated as in LCD , except ad15.ad15 determines selection of LCD or LCD . It can be use the address decoded signal /ce0(0000 to 07FFH), /ce1(0800 to 0FFFH) within 4 KB. /ce0 and /ce1 allow decoding of address in the ranges(0000 to 07FFH) and(0800 to 0fffH) respectively within a 4-KB memory space.
