For testing. Fix to “L”
Parallel/Serial interface select pin.
P/S = “H”: For parallel interface
P/S = “L”: For serial interface. Fix D15-D5 pins to Hi-Z, and fix RDB and
WRB pins to either “H” or “L”
Segment output pins for the LCD driver.
Basing on the Display RAM data, non-lighted at “0”, lighted at “1”
(Normal Mode), non-lighted at “1”, lighted at “0” (Reverse Mode) and
by a combination of M signal and display data, one signal level among
V0, V2, V3 and VSS signal level is selected.
(For Monochrome Display)
Common output pins for the LCD drivers. By a combination of the
scanning data and M signal, one signal level among V0, V1, V4 and
VSS signal level is selected.
Common output pin for LCD drive exclusively for icons.
