TRON
0: Normal mode (all values written to the test register are ignored)
1: Test register valid mode (values written to the test register are valid)
WAS
0: Normal data write mode
1: Window access mode (Refer to
5.2.7 Arbitrary address area access (window access mode (WAS))
.)
COMF
0: Normal display operation
1: All output from common pins is OFF (all the common pins output a non-selected waveform. At this time, the
segment pins output OFF data (level 0)).
DISP
0: Display OFF (All the LCD output pins output a V
SS
level, and the oscillator and DC/DC converter operate.)
1: Display ON
STBY
0: Normal operation
1: Internal operation and oscillation stop. Display OFF
HALT
0: Internal operation starts.
1: Internal operation stops (all the LCD output pins output a V
SS
level, the oscillator operates, and the DC/DC
converter stops, and the reference voltage generator operates).
Column addresses correspond to SEG outputs that are used to display the display data RAM (refer to
Table 6
1
).
Selects the direction in which the lines of the graphic RAM are read (refer to
Table 6
