CHAPTER 6 16-BIT TIMER/EVENT COUNTER P (TMP)
Initial setting of these
registers is performed
before setting the
TPnCE bit to 1.
The TPnCKS0 to
TPnCKS2 bits can be
set at the same time
when counting is
enabled (TPnCE bit = 1).
Trigger wait status
TPnCCR1 register write
processing is necessary
only when the set
cycle is changed.
When the counter is
cleared after setting,
the value of the TPnCCRm
register is transferred to
the CCRm buffer register.
