(c) Notes on rewriting TQ0CCR0 register
When rewriting the value of the TQ0CCR0 register to a smaller value, stop counting first and then change
the set value.
If the value of the TQ0CCR0 register is rewritten to a smaller value during counting, the 16-bit counter may
overflow.
Remark
If the value of the TQ0CCR0 register is changed from D
but less than D
register has been rewritten. Consequently, the value that is compared with the 16-bit counter value is D
Because the counter value has already exceeded D
overflows, and then increments again from 0000H. When the counter value matches D
signal is generated and the output of the TOQ00 pin is inverted.
Therefore, the INTTQ0CC0 signal may not be generated at the interval “(D

“(10000H + D
