TRDE#	D11	O	Transceiver Data Enable Control. Active low for	GPIO0
			Sub-ISA data transfers. The signal timing is as fol-
			lows:
			• In a read cycle, TRDE# has the same timing as
			RD#.
			• In a write cycle, TRDE# is asserted (to active
			low) at the time WR# is asserted. It continues
			being asserted for one PCI clock cycle after
			WR# has been negated, then it is negated.

RD#	B8	O	Memory or I/O Read. Active on any read cycle.	CLKSEL0 (Strap)

WR#	B9	O	Memory or I/O Write. Active on any write cycle.	---

IOR#	D9	O	I/O Read. Active on any I/O read cycle.	DOCR#+GPIO14

IOW#	A8	O	I/O Write. Active on any I/O write cycle.	DOCW#+GPIO15

DOCR#	D9	O	DiskOnChip or NAND Flash Read. Active on any	IOR#+GPIO14
			memory read cycle to DiskOnChip.

DOCW#	A8	O	DiskOnChip or NAND Flash Write. Active on	IOW#+GPIO15
			any memory write cycle to DiskOnChip.

IRQ9	AA3	I	Interrupt 9 Request Input. Active high.	IDE_DATA6
			Note: If IRQ9 function is selected but not used,
			tie IRQ9 low.

IOCHRDY	C9	I	I/O Channel Ready	GPIO19+INTC#
			Note: If IOCHRDY function is selected but not
			used, tie IOCHRDY high.
