Watchdog Timer
Port Pins
If the watchdog timer is not needed in the application, the module should be turned off. If the
watchdog timer is enabled, it will be enabled in all sleep modes and, hence, always consume
power. Refer to
watchdog timer.
When entering a sleep mode, all port pins should be configured to use minimum power. Most
important is to ensure that no pins drive resistive loads. In sleep modes where the Peripheral
Clock (Clk
power is consumed by the input logic when not needed.
