Segment output pins for LCD drives.
According to the data of 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 levels are
selected.
Display timing clock source select input pin.
CKS = “H”: Use external clock from CK pin.
CKS = “L”: Use internal oscillated clock.
External clock input pin for display timing (CKS=1) or internal clock output pin for
display timing (CKS=0).
When using internal oscillated clock, CK must be floating (CKS=0)
Common output pins for 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.
