6.4 Operation of 16-Bit Timer/Event Counter 00
6.4.1 Interval timer operation
mode entered upon a match between TM00 and CR000), the count operation is started in synchronization with the
count clock.
(INTTM000) is generated. This INTTM000 signal enables TM00 to operate as an interval timer.
If bits 3 and 2 (TMC003 and TMC002) of the 16-bit timer mode control register (TMC00) are set to 11 (clear & start
When the value of TM00 later matches the value of CR000, TM00 is cleared to 0000H and a match interrupt signal
