rn_enable_wdt

int rn_enable_wdt(int handle, int wdttype);

FUNCTION 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 soft-
ware 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.

PARAMETERS

handle

address index to device information. Use

rn_device()

or

rn_find()

to establish the handle.

wdttype

0 enables both hardware and software watchdog timers
1 enables hardware watchdog timer
2 enables software watchdog timer

RETURN VALUE

The status byte from the previous command. -1 means that device information indicates
the peripheral card is not connected to the master.
