Preliminary
for TCP2. At the same time, interrupt request flag TCPxF will set activated, if
software enables the corresponding interrupt enable bit, INT hardware will
cause MCU interrupt service routine.
.Counter
Counter feature is implemented only by TCPxLD=0, the TCPxD can be zero
or not that depends on software needs. User starts and stops the counter by
changing the TCPxEN bit value. On the save side, reading the counter value
after stopping the count by disable TCPxEN=0, if reading the counter value
during value changing that means clock in happening at the same time. The
reading of counter value may disrupt for transient state. If 8-bit counter is not
enough for counting, user can enable the interrupt and using the data RAM as
software counter for extending the counter stage.
