DESCRIPTION
Reserved. Bits 15−7 return 0s when read.
15−7
6−5 ‡
INT_SEL
RW
Interrupt select. These bits are program the INTPIN register and set which interrupt output is used.
This field is ignored if one of the USE_INTx terminals is asserted.
00 = INTA (pin = 1)
01 = INTB (pin = 2)
10 = INTC (pin = 3)
11 = INTD (pin = 4)
4 ‡
D3_COLD
RSVD
RW
R
Disable function. Setting this bit to 1 hides this function. PCI configuration register of this function
must be accessible at any time. Clock (PCI and 48 MHz) to the rest of the function blocks must be
gated to reduce power consumption.
3−0
Reserved. Bits 3−0 return 0s when read.
‡
One or more bits in this register are cleared only by the assertion of GRST.
