Preliminary User’s Manual U17566EE1V2UM00
To change the PWM waveform while the counter is operating, write the
TPnCCR1 register last.
Rewrite the TPnCCRm register after writing the TPnCCR1 register after
the INTTPnCC0 signal is detected.
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.
