(5) One-shot mode
In down count operation, the count stops when an underflow event (transition from “0000
H
” to “FFFF
H
”) occurs.
This function can generate an interrupt at each underflow. While the counter is operating, a rectangular wave
form indicating that the count is in progress can be output form the TOT0 and TOT1 pins.
