2.9.8. Control Registers
All control registers for the PWM are mapped in the
SFR address space. Their address and bit description
are given below.
Note that the controller can write any time into these
registers.
PWM_CPMP14_X and PWM_CPMPEXT14_X, includ-
ing the bits PWM_direct and PWM_PR are double
buffered and values from shadow registers are only

loaded into the main register in case timer overflows or
timer is stopped (PWME = 00
Overflow for 8 bit PWM occurs at the overflow of 6 bit
counter and overflow for 14 bit counter occurs at the
overflow.
When any of the PWM channels is not used associ-
ated compare register can be used as general purpose
registers, except PWM_En and PWCOMPEXT14_0 bit
0 and 1.
