7.6 RESET CONDITIONS
After either a power-up reset or an external reset, the module initializes to the following
conditions:
1) All DDRAM locations are set to 20H (character code for a space).
2) The AC is set to DDRAM address 00H (i.e. sets cursor position to 00H).
3) The relationship between DDRAM addresses and character positions on the VFD is set to the
non-shifted position.
4) Entry Mode Set instruction bits:
I/D = 1: The AC increments after each DDRAM or CGRAM access.
S = 0: The display shift function is disabled.
5) Display On/Off Control instruction bits:
D = 0: The display is off (display blank).
C = 0: The cursor is off.
B = 0: The blinking character function is disabled.
6) Function Set instruction bits:
DL = 1: Sets the data bus width for the parallel interface modes to 8-bit (DB7-DB0).
N = 1(0): Number of display lines set to 2 for multiple line displays (number of display
lines set to 1 for single line displays).
BR1,BR0 = 0,0: Sets the luminance level to 100%.
Note that the function set command must be the first instruction sent to the module after any
reset.
7.6.1 INITIALIZATION
The module can be initialized by using instructions if the module is not reset according to the
reset timing detailed in Section 3.7.1 (Reset Timing). After any reset, the function set command
must be the first instruction sent to the module.
