Bit 4: PBKF, PWM Break Flag. This bit is set by PWM break source enabled. If this flag is set, the
enabled PWM channel 0~5 will be blocked and the output pins keep the original GPIO state.
0: There is no PWM Break event happened. It is only cleared by software.
1: There is a PWM Break event happened or software triggers a PWM Break.

PCA Module Output Control
PCA0 modules have multi output control mode can be selected for different applications. The CEXn
(n=1,3,4,5,6,7) can be programed as general I/O port or the output of the PCA0 module (PWM) 1, 3, 4, 5, 6
and 7. When PWM has been assigned to the CEXn, the PnINV can switch between the normal PWM signal or
inverted PWM signal. POEn can be used to enable or disable the PWM output to the port pin.
The CEXn (n=1,3,4,5) also can use PBKF, PWM Break Flag, to break PWM output. If this flag is set, the
enabled PWM channel 0~5 will be blocked and the output pins keep the original GPIO state.
In addition, PCA0 module 0 and 2 have 2 “Cloned” signals to the different port pin. These three the same
PWM signals can be masked particular cycles by the POEnA or POEnB or PWMn for the applications which
need phase control.
