If PSW of TCA reset is selected while the LCD is operating, LCD operation halts (power switch
goes off and all SEG and COM pins are grounded).
When an LCD is connected for display, the PSW and TCA reset periods must be set in the
program to the minimum.
The division ratio must not be modified during time-base mode operation, otherwise an overflow
cycle error will occur.
