rn_enable_wdt
int rn_enable_wdt(int handle, int wdttype);
DESCRIPTION
Enables the hardware and/or software watchdog timers on a peripheral card. The soft-
ware on the peripheral card will keep the hardware watchdog timer updated, but will hard
reset if the time expires. The hardware watchdog cannot be disabled except by a hard
reset on the peripheral card. The software watchdog timer must be updated by software
on the master. The peripheral card will soft reset if the timeout set by
rn_sw_wdt()
expires.
This function will
check device information to determine that the peripheral card
is connected to a master.
