Bit 1 = OPx PWMx Output Polarity.
This bit is read/write by software and cleared by hardware after a reset. This bit selects the
polarity of the PWM signal.
0: The PWM signal is not inverted.
1: The PWM signal is inverted.
Bit 0 = CMPFx PWMx Compare Flag.
This bit is set by hardware and cleared by software by reading the PWMxCSR register. It
indicates that the upcounter value matches the DCRx register value.
0: Upcounter value does not match DCR value.
1: Upcounter value matches DCR value.
Break control register (BREAKCR)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:6 = Reserved. Forced by hardware to 0.
Bit 5 = BA Break Active.
This bit is read/write by software, cleared by hardware after reset and set by hardware when
the BREAK pin is low. It activates/deactivates the Break function.
0: Break not active
1: Break active
Bit 4 = BPEN Break Pin Enable.
This bit is read/write by software and cleared by hardware after Reset.
0: Break pin disabled
1: Break pin enabled
Bits 3:0 = PWM[3:0] Break Pattern.
These bits are read/write by software and cleared by hardware after a reset. They are used
to force the four PWMx output signals into a stable state when the Break function is active.
