16-Bit Timer/Counter
6.3.1
16-Bit timer/counter functions
16-bit timer/counter 90 (TM90) has the following functions.
(1) Timer interrupt
An interrupt is generated if the TM90 count matches a comparison value.
(2) Timer output
The timer output can be controlled if the count matches a comparison value.
(3) Count capture
The count in TM90 is captured into the capture register in synchronization with a capture trigger.
(4) Buzzer output
The buzzer output can be controlled if the count matches the comparison value.
6.3.2
