Entry Mode Register (R0)
The entry mode register (Figure 6) includes bits I/D, RM1, and RM0.
I/D:
Increments (I/D = 1) or decrements (I/D = 0) the DDRAM address by 1 when a character code is
written into or read out from the DDRAM. When the DDRAM address is incremented by 1, the cursor or
blinking will also shift to the right. This applies to both CGRAM and SEGRAM.
RM1/0:
Selects DDRAM, CGRAM, or SEGRAM for access (Table 10).
