DESCRIPTION OF PIN FUNCTIONS

PIN NO.	NAME	SYMBOL	TYPE	DESCRIPTION
	nInterrupt	nIREQ		PCMCIA - Active low interrupt request output.
	Request			Pin acts as a Ready pin during power-up. The
				pin should be pulled low within 10us of the
				application of the VCC or Reset (which ever
				occurs later). It remains low(0) until the CIS is
				loaded in the Internal SRAM. The high(1)
				state indicates to the host controller that the
				device is ready.
91	Interrupt 1	INTR1	O24	ISA - Output. Active high interrupt signal. The
				interrupt line selection is determined by the
				value of INT SEL1-0 bits in the Configuration
				Register. This interrupt is tri-stated when not
				selected.
		nINPACK		PCMCIA - Output asserted to acknowledge
				read cycles for an enabled function.
92	Interrupt 2	INTR2	O24	ISA - Output. Active high interrupt signal. The
				interrupt line selection is determined by the
				value of INT SEL1-0 bits in the Configuration
				Register. This interrupt is tri-stated when not
				selected.
	nStatus	nSTSCHG		PCMCIA - Status changed bit. Depending on
	Changed			the setting of the RingEn bit (Modem CCSR),
				this pin either reflects the ringing status (ExCA
				mode) or the state of the Modem Changed bit.
				The ringing status is obtained by stretching
				the MRINGIN to convert a 20Hz toggle rate to
				a constant level.
93	Interrupt 3	INTR3	O24	ISA - Output. Active high interrupt signal. The
				interrupt line selection is determined by the
				value of INT SEL1-0 bits in the Configuration
				Register. This interrupt is tri-stated when not
				selected.
85	nI/O 16	nIOCS16	OD24	ISA - Active low output asserted in 16 bit
				mode when AEN is low and A4-A15 decode
				to the SMC91C95 address programmed into
				the high byte of the Base Address Register.
