CR000), the counting operation is started in synchronization with the count clock.
(INTTM000) is generated, and TO00 output is inverted. This TO00 output that is inverted at fixed intervals enables
TO0n to output a square wave.

When 16-bit timer/event counter 00 operates as an interval timer (refer to 6.4.1), a square wave can be output from
When TMC003 and TMC002 are set to 11 (count clear & start mode entered upon a match between TM00 and
When the value of TM00 later matches the value of CR000, TM00 is cleared to 0000H, an interrupt signal
