FD2000
Rev1.0
7. RESET FUNCTION
The FD2000 is reset when a low level is applied to the RESETB pin at power on and, in normal mode. On a reset
the FD2000 create a display with all LCD panels turned off. However, after a reset applications must set the
contents of DCRAM, ADRAM, and CGRAM before turning on display with a “display on/off control” instruction
since the contents of these memories are undefined. That is, applications must execute the following instructions.
− Set display technique
− DCRAM data write
− ADRAM data write (If ADRAM is used.)
− CGRAM data write (If CGRAM is used.)
− Set AC address
After executing the above instructions, applications must turn on the display with a “display on/off control”
instruction. Note that when applications turn off in the normal mode, applications must turn off the display with a
“display on/off control” instruction. (See the detailed instruction descriptions.)
