DIGITAL WATCHDOG (Cont’d)

These instructions test the C bit and Reset the

MCU (i.e. disable the Watchdog) if the bit is set

(i.e. if the Watchdog is active), thus disabling the

Watchdog.

In all modes, a minimum of 28 instructions are ex-

ecuted after activation, before the Watchdog can

generate a Reset. Consequently, user software

should load the watchdog counter within the first

27 instructions following Watchdog activation

(software mode), or within the first 27 instructions

executed following a Reset (hardware activation).

It should be noted that when the GEN bit is low (in-

terrupts disabled), the NMI interrupt is active but

cannot cause a wake up from STOP/WAIT modes.
