PS1–0:
Specify PS1 to PS0 bits when SW = 1. When PS1–0 = 01, only the first line is fixed-displayed in
vertical smooth scrolling, and the other display lines are smooth-scrolled. When PS1–0 = 10, the first and
second lines are fixed-displayed. When PS1–0 = 11, the first to third lines are fixed-displayed. For details,
see the Partial Smooth Scroll Display Function section.
CGROM Bank Control 1/2
RL6–1:
Set RL1 to RL6 bits when SW = 0. Switch the CGROM memory bank for any line. Bank 0 and
bank 1 of the CGROM incorporate 240 and 192 fonts, respectively, and can display 432 fonts in total. Bits
RL1–RL6 select CGROM bank 0/1 for each display line unit. When RL1 = 0, the first line selects bank 0.
When RL1 = 1, the first line selects bank 1. Bits RL2, RL3, RL4, and RL6 select the memory banks in the
second to sixth lines. For details, see the CGROM Bank Switching Function section.
RL10–7:
Set the RL7 to RL10 bits when SW = 1. The RL7 to RL10 bits are set when SW = 1. And the
DL7 to DL10 bits switch the CGROM memory bank in the seventh to 10th lines.
