MFUNC1
RW
Multifunction terminal 1 configuration. These bits control the internal signal mapped to the MFUNC1 terminal
as follows:
0000 = GPI1
0100 = OHCI_LED
1000 = CAUDPWM
1100 = LEDA1
0001 = GPO1
0101 = IRQ5
1001 = IRQ9
1101 = RSVD
0010 = INTB
0110 = RSVD
1010 = IRQ10
1110 = GPE
0011 = IRQ3
0111 = RSVD
1011 = IRQ11
1111 = IRQ15
30
MFUNC0
RW
Multifunction terminal 0 configuration. These bits control the internal signal mapped to the MFUNC0 terminal
as follows:
0000 = GPI0
0100 = IRQ4
1000 = CAUDPWM
1100 = LEDA1
0001 = GPO0
0101 = IRQ5
1001 = IRQ9
1101 = RSVD
0010 = INTA
0110 = RSVD
1010 = IRQ10
1110 = GPE
0011 = IRQ3
0111 = RSVD
1011 = IRQ11
1111 = IRQ15
These bits are cleared only by the assertion of GRST.
4.36 Retry Status Register
The contents of the retry status register enable the retry time-out counters and display the retry expiration
status. The flags are set when the controller, as a master, receives a retry and does not retry the request within
215 clock cycles. The flags are cleared by writing a 1b to the bit. See Table 415 for a complete description
of the register contents.
PCI register offset:

FUNCTION

PCIRETRY
RW
PCI retry time-out counter enable. This bit is encoded as:
0 = PCI retry counter disabled
1 = PCI retry counter enabled (default)
6 §
CBRETRY
RW
CardBus retry time-out counter enable. This bit is encoded as:
0 = CardBus retry counter disabled
1 = CardBus retry counter enabled (default)
5
TEXP_CBB
RC
CardBus target B retry expired. Write a 1b to clear this bit.
0 = Inactive (default)
1 = Retry has expired
4
RSVD
R
Reserved. This bit returns 0b when read.
3 §
TEXP_CBA
RC
CardBus target A retry expired. Write a 1b to clear this bit.
0 = Inactive (default)
1 = Retry has expired
2
RSVD
R
Reserved. This bit returns 0b when read.
1
TEXP_PCI
RC
PCI target retry expired. Write a 1b to clear this bit.
0 = Inactive (default)
1 = Retry has expired
0
RSVD
R
Reserved. This bit returns 0b when read.
This bit is cleared only by the assertion of GRST.
§ These bits are global in nature and must be accessed only through function 0.
