60.6.3.3.6 Scheduled Pull-Up/Pull-Down

In order to reduce the power consumption on the VBAT power supply, all activated pull-ups/pull-downs can be scheduled by following the steps below:

  1. Activate the required pull-up/pull-down.
  2. Measure the level on the PIOBUx pin.
  3. Deactivate the pull-up/pull-down.

Scheduling is enabled by setting SECUMOD_PIOBUx.SCHEDULE.

Note: This feature is only effective if SECUMOD_PIOBUx.PULLUP= '1' or '2', indicating that a pull-up or a pull-down is connected.
