BREAK CONTROL REGISTER (BREAKCR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = BRSEL Break Input Selection
This bit is read/write by software and cleared by
hardware after reset. It selects the active Break
signal from external BREAK pin and the output of
the comparator.
0: External BREAK pin is selected for break mode.
1: Comparator output is selected for break mode.
Bit 6 = BREDGE Break Input Edge Selection
This bit is read/write by software and cleared by
hardware after reset. It selects the active level of
Break signal.
0: Low level of Break selected as active level.
1: High level of Break selected as active level.
Bit 5 = BA Break Active.
This bit is read/write by software, cleared by hard-
ware after reset and set by hardware when the ac-
tive level defined by the BREDGE bit is applied on
the BREAK pin. 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 and correspond-
ing OEx bit is set.

PWMx DUTY CYCLE REGISTER HIGH (DCRxH)
Read / Write
Reset Value: 0000 0000 (00h)
Bits 15:12 = Reserved.
PWMx DUTY CYCLE REGISTER LOW (DCRxL)
Read / Write
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
Compare mode, they define the value to be com-
pared with the 12-bit upcounter value.
INPUT CAPTURE REGISTER HIGH (ATICRH)
Read only
Reset Value: 0000 0000 (00h)
Bits 15:12 = Reserved.
INPUT CAPTURE REGISTER LOW (ATICRL)
Read only
Reset Value: 0000 0000 (00h)
