(b) Notes on rewriting the TPnCCR0 register
To change the value of the TPnCCR0 register to a smaller value, stop counting once and then change the set
value.
If the value of the TPnCCR0 register is rewritten to a smaller value during counting, the 16-bit counter may
overflow.
Remark
If the value of the TPnCCR0 register is changed from D
than D
rewritten. Consequently, the value that is compared with the 16-bit counter is D
Because the count value has already exceeded D
and then counts up again from 0000H. When the count value matches D
Therefore, the INTTPnCC0 signal may not be generated at the valid edge count of “(D
