Description

Safe State Control

Fields

PB0SSSEL

Port Bank n.0 Safe State Select.

0 (HIZ): Place PBn.0 in a High Impedance state.

1 (HIGH): Drive PBn.0 High.

2 (LOW): Drive PBn.0 Low.

3 (DISABLED): Ignore the safe state signal (weak pull-ups disabled).

PB1SSSEL

Port Bank n.1 Safe State Select.

0 (HIZ): Place PBn.1 in a High Impedance state.

1 (HIGH): Drive PBn.1 High.

2 (LOW): Drive PBn.1 Low.

3 (DISABLED): Ignore the safe state signal (weak pull-ups disabled).

PB2SSSEL

Port Bank n.2 Safe State Select.

0 (HIZ): Place PBn.2 in a High Impedance state.

1 (HIGH): Drive PBn.2 High.

2 (LOW): Drive PBn.2 Low.

3 (DISABLED): Ignore the safe state signal (weak pull-ups disabled).

PB3SSSEL

Port Bank n.3 Safe State Select.

0 (HIZ): Place PBn.3 in a High Impedance state.

1 (HIGH): Drive PBn.3 High.

2 (LOW): Drive PBn.3 Low.

3 (DISABLED): Ignore the safe state signal (weak pull-ups disabled).

PB4SSSEL

Port Bank n.4 Safe State Select.

0 (HIZ): Place PBn.4 in a High Impedance state.

1 (HIGH): Drive PBn.4 High.

2 (LOW): Drive PBn.4 Low.

3 (DISABLED): Ignore the safe state signal (weak pull-ups disabled).

PB5SSSEL

Port Bank n.5 Safe State Select.

0 (HIZ): Place PBn.5 in a High Impedance state.

1 (HIGH): Drive PBn.5 High.

2 (LOW): Drive PBn.5 Low.

3 (DISABLED): Ignore the safe state signal (weak pull-ups disabled).

SSMDEN

Enter Safe State Mode.

0 (DISABLED): Disable Safe State.

1 (ENABLED): Enter Safe State. Each PBn.x pin will enter the states defined by PBxSSSEL.

PBSSSMD

Safe State Signal Mode.

0 (DEGLITCH): Enable deglitching on the kill signal input. The kill signal must be asserted for two APB clocks to be recognized.

1 (IMMEDIATE): Disable deglitching on the kill signal input. The kill signal will take immediate effect.
