Preliminary W79E217A Data Sheet
All the bits in this SFR have unrestricted read access. The bits of POR, WDIF, EWT and RWT require
Timed Access (TA) procedure to write. The remaining bits have unrestricted write accesses. Please

PWMRUN
0 = The PWM is not running.
1 = The PWM counter is running.
6 Load
This bit is auto cleared by hardware after the PWMP and PWMn are transferred
to counter and compare register:
0 = The registers value of PWMP and PWMn is never loaded to counter and
compare registers.
1 = The PWMP and PWMn registers load value to counter and compare
registers at the counter underflow/match.
