6.118 WDG4

WDG Module

Function

The WDT failsafe can be disabled

Description

The UCS is capable of masking clock requests (ACLK, SMCLK, MCLK) from peripheral modules; see request enable (REQEN) bits in the UCS control register, UCSCTL8.

The clock request logic of the UCS is used by the WDT module to ensure a fail-safe clock source in all low-power modes. Therefore, de-asserting the request enable bit of the watchdog clock source (xCLKREQEN = 0) allows the respective clock to be disabled upon entry into a low-power mode. Without an active clock source, the WDT timer stops incrementing and a watchdog event will not occur.

Workaround

None
