Notes

1. The Restart and Soft Reset Value depends on the respective GPIO configuration. Therefore the bit type is also

‘rwhl’ and the restart value is ‘y’. See also Table 22 in Chapter 11.1.2 for more information on the GPIO

behavior for the different SBC modes and Restart behavior.

2. In case the CFG_LOCK_0 bit is set, then the soft reset value is like the Restart value.

3. If GPIO is configured as a wake input, then it is a default wake source in SBC Fail-Safe Mode .

Notes

1. 0% and 100% duty cycle settings are used to have the switch turned On or Off respectively.

2. A new duty cycle configuration will become effective after the previous period is completed.

3. The desired duty cycle should be set first before GPIO is enabled as PWM HS or PWM LS.
