: Address retention
When auto increment is used, the address is automatically
up-counted after a full-dot, character, or CGRAM data write.
The character X address is reset to 13H.
When address retention is specified, the address is retained
after a data write.
Frame frequency setting
00: 100 Hz
01: 75 Hz
10: 50 Hz
11: Don’t Care
LCD drive is performed by frame inversion.
Blink source setting
0: External clock (OSC3)
1: Internal scaled block
Master/slave setting
