(b) Notes on rewriting TPnCCR0 register
When rewriting the value of the TPnCCR0 register to a smaller value, stop counting first 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
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 up again from 0000H.
INTTPnCC0 signal is generated.
Therefore, the INTTPnCC0 signal may not be generated at the valid edge of the external event count
signal when the external event count is “(D
generated at the valid edge of the external event count signal when the external event count is “(10000H +
