IP2022 User’s Manual—In-System Programming www.ubicom.com 369 WDPS2:0 Specifies the Watchdog Timer prescaler divisor. This controls
the time period before the Watchdog Timer expires. If the
Watchdog Timer is enabled, software must clear the Watch-
dog Timer periodically within this time period to prevent a reset
of the IP2022 from occurring. The cwdt instruction or a reset
from the RST pin clears both the Watchdog Timer and its pres-
caler. 000 =   1 (~20 ms)
