Bit 4 = BP2EN Break 2 pin enable bit
Bits 3:2 = Reserved, must be kept cleared
Bit 1 = SWBR2 Switch Break for counter 2 bit
Bit 0 = SWBR1 Switch Break for counter 1 bit
PWMx duty cycle register High (DCRxH)
Reset value: 0000 0000 (00h)
Bits 15:12 = Reserved.
PWMx duty cycle register Low (DCRxL)
Reset value: 0000 0000 (00h)
Bits 11:0 = DCRx[11:0] PWMx Duty Cycle Value: this 12-bit value is written by software. It
defines the duty cycle of the corresponding PWM output signal (see
In PWM mode (OEx=1 in the PWMCR register) the DCR[11:0] bits define the duty cycle of
the PWMx output signal (see

This bit is read/write by software and cleared by hardware after Reset.
0: BREAK2 pin disabled
1: BREAK2 pin enabled
This bit is read/write by software. While BREN2 is set, it selects BA1 or BA2 to control
PWM2/3 if ENCNTR2 bit is set.
0: BA1 selected
1: BA2 selected
This bit is read/write by software. While BREN1 is set, it selects BA1 or BA2 to control
PWM0/1 by default and also PWM2/3 if ENCNTR2 bit is reset.
