(d) Notes on rewriting TT0CCR0 register
If the value of the TT0CCR0 register is rewritten to a smaller value during counting, the 16-bit counter may
overflow. When an overflow may occur, stop counting once and then change the set value.
If the value of the TT0CCR0 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 INTTT0CC0 signal may not be generated at the valid edge count of “(D
times” as originally expected, but may be generated at the valid edge count of “(10000H + D
