The LCTC display mode is determined by pins D/
S
(pin 55), G/
C
(pin 58), LS (pin 56), WIDE (pin 54), and
AT (pin 57). As for G/C, WIDE, and AT, the OR is taken between data bits 0, 2, and 3 of the mode register
(R22). The display mode can be controlled by either one of the external pins or the data bits of R22.
Note:
The above 5 pins have 32 status combinations (high and low). Any combinations other than the
above are prohibited, because they may cause malfunctions. If you set an prohibited combination,
set the right combination again.
