8.2.1 Description
Start the watchdog timer and set the parameters. To adjust the parameters, the watchdog must be
stopped via EApiWDogStop and then EApiWDogStart must be called again with the new values.
If the hardware implementation of the watchdog timer does not allow to set exactly the selected timing,
the EAPI shall select the next possible longer timing.
8.2.2 Parameters
uint32_t
EAPI_CALLTYPE
EApiWDogStart(
__IN uint32_t delay , /* Delay in msec */
__IN uint32_t EventTimeout /* Timeout in msec */
__IN uint32_t ResetTimeout /* Reset in msec */
);
FUNC_DEF 18: EApiWDogStart
delay
__IN Initial delay for the watchdog timer in milliseconds.
The first trigger must happen within (delay + EventTimeout) milliseconds, of calling EApiWDogStart.
EventTimeout
__IN Watchdog timeout interval in milliseconds to trigger an event.
ResetTimeout
__IN Watchdog timeout interval in milliseconds to trigger a reset.
