DISPLAY
Initialized. No display appears.
During the acknowledge cycle SDA will be pulled-down by the
PCF2116.
Control byte sets RS and R/W for following data bytes.
Selects 1-line display and V
acknowledge cycle starts execution of instruction.
Turns on display and cursor. Entire display shows character
Hex 20 (blank in ASCII-like character sets).
Sets mode to increment the address by 1 and to shift the cursor
to the right at the time of write to the DDRAM or CGRAM.
Display is not shifted.
For writing data to DDRAM, RS must be set to 1. Therefore a
control byte is needed.
Writes ‘P’. The DDRAM has been selected at power-up.
The cursor is incremented by 1 and shifted to the right.
