Bit 7 = BR2SEL Break 2 input selection bit
Bit 6 = BR2EDGE Break 2 input edge selection bit
Bit 5 = BA2 Break 2 Active bit
BR2SEL
This bit is read/write by software and cleared by hardware after reset. It selects the
active level of Break 1 signal.
0: Low level of Break 1 selected as active level
1: High level of Break 1 selected as active level
This bit is read/write by software, cleared by hardware after reset and set by hardware
when the active level defined by the BR1EDGE bit is applied on the BREAK1 pin. It
activates/deactivates the Break 1 function.
0: Break 1 not active
1: Break 1 active
This bit is read/write by software and cleared by hardware after Reset.
0: Break 1 pin disabled
1: Break 1 pin enabled
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 corresponding OEx bit is set.
This bit is read/write by software and cleared by hardware after reset. It selects the
active Break 2 signal from external BREAK2 pin and the output of the comparator.
0: External BREAK2 pin is selected for break mode.
1: Comparator 2 output is selected for break mode.
This bit is read/write by software and cleared by hardware after reset. It selects the
active level of Break 2 signal.
0: Low level of Break 2 selected as active level
1: High level of Break 2 selected as active level
This bit is read/write by software, cleared by hardware after reset and set by hardware
when the active level defined by the BR2EDGE bit is applied on the BREAK2 pin. It
activates/deactivates the Break 2 function.
0: Break 2 not active
1: Break 2 active
