s (when a 32.768-kHz crystal oscillator is used)
Timer counter overflow output period (seconds) = input clock period (seconds) 256.
If PSW or 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.
