(b) Notes on rewriting the TQ0CCR0 register
To change the value of the TQ0CCR0 register to a smaller value, stop counting once 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.
If the value of the TQ0CCR0 register is changed from D
less than D
has been rewritten. Consequently, the value that is compared with the 16-bit counter 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.
Therefore, the INTTQ0CC0 signal may not be generated at the valid edge count of “(D
+ 1) times” originally expected, but may be generated at the valid edge count of “(10000H + D
