Function Documentation

hudson_configure_gevent_smi()

void hudson_configure_gevent_smi	(	uint8_t	gevent,
		uint8_t	mode,
		uint8_t	level
	)

Configure generation of interrupts for given GEVENT pin.

Parameters

gevent	The GEVENT pin number. Valid values are 0 thru 23
mode	The type of event this pin should generate. Note that only SMI_MODE_SMI generates an SMI. SMI_MODE_DISABLE disables events.
level	SMI_LVL_LOW or SMI_LVL_HIGH
