(Invalid area)
COMS2
A
Notes: 1. When the RM1/0 bit is set to "11", the SEGRAM can be selected.
2. Writing to the lower four bits (DB0–DB3) in the SEGRAM is invalid.
3. The segment output that can be controlled by grayscale is enabled for only the 40 segments (table 9).
These grayscale-controlled segments are driven by the same grayscale data at COMS1 and COMS2 selection.
4. Other outputs than the grayscale-controlled segment outputs can control segment on/off and blinking. The
COMS1 and COMS2 outputs are independently controlled.
