9.5
(1) Error on starting timer
(2) Rewriting the TM0CMP0 and TM0CTL0 registers is prohibited while TMM0 is operating.
Cautions
It takes one clock to generate the first compare match interrupt request signal (INTTM0EQ0) after the
TM0CTL0.TM0CE bit is set to 1 and TMM0 is started. This is because the value of the 16-bit counter is FFFFH
when the TM0CE bit = 0 and TMM0 is started asynchronously to the count clock.
If these registers are rewritten while the TM0CTL0.TM0CE bit is 1, the operation cannot be guaranteed.
If they are rewritten by mistake, clear the TM0CE bit to 0, and re-set the registers.
