14.6.2.4 Watchdog Service Register
MMC2114 • MMC2113 • MMC2112 — Rev. 1.0
MOTOROLA
Address: 0x00c7_0006 and 0x00c7_0007
When the watchdog timer is enabled, writing 0x5555 and then 0xAAAA
to the Watchdog Service Register (WSR) before the watchdog counter
times out prevents a reset. If WSR is not serviced before the timeout, the
watchdog timer sends a signal to the reset controller module which sets
the WDR bit and asserts a system reset.
Both writes must occur in the order listed before the timeout, but any
number of instructions can be executed between the two writes.
However, writing any value other than 0x5555 or 0xAAAA to WSR resets
the servicing sequence, requiring both values to be written to keep the
watchdog timer from causing a reset.
