Counter Mode with Low Level Active Gate Control
In this mode, the gate input affects counter operation. Once started,
the counter will count to TC repetitively. The counter will count all
source edges that occurred while the gate low level is active and
disregard those edges that occurred while the gate is inactive.
On each TC the counter will reload the initial value of counter from
the counter set value register (Base Add. + 18h). The counter output
mode may be obtained with the TC output mode or the TC toggled
output mode by specifying in the Counter Mode register (CM5, CM4);
Toggled output uses the trailing edge of TC to toggle a flip-flop to
generate an output level instead of a pulse. During the TC Toggled
output mode, it will hold high output level and ignore the following
TCs until users clear the toggled output by writ ing the Bit1 of Count
Reset Register (Base Add. + Eh ). If Bit0 of the Count Reset Register
