(c) Notes on rewriting TTnCCR0 register
If the value of the TTnCCR0 register is rewritten to a smaller value during counting, the 16-bit counter may
overflow. When an overflow may occur, stop counting and then change the set value.
Remarks 1. Interval time (1):
If the value of the TTnCCR0 register is changed from D
less than D
has been rewritten. Consequently, the value of the 16-bit counter that is compared is D
Because the count value has already exceeded D
overflows, and then counts up again from 0000H. When the count value matches D
signal is generated and the output of the TOTm0 pin is inverted.
Therefore, the INTTTEQCn0 signal may not be generated at the interval time “(D
or “(D
+ 1) × Count clock cycle”.
