Bit
Bit Name Value R/W Description
15 to 11 DN
Undefined SH: R/W Device Number
PCI:  Specify the device number for a configuration access.
Device numbers ranging from 0 to 31 are represented
in five bits.
A single bit of bits 31 to 16 of the AD signals is driven
to high level instead of the IDSEL assertion. The bit
driven to high level corresponds to the device number
set in these bits. The correspondence between the
device number and IDSEL (AD[31:16]) is shown
below. If a device number is equal to H'10 or greater,
all bits 31 to 16 of the AD signals are driven to low
level.
Device No. IDSEL
Device No. IDSEL
H'0: AD[16] = high level H'8: AD[24] = high level
H'1: AD[17] = high level H'9: AD[25] = high level
H'2: AD[18] = high level H'A: AD[26] = high level
H'3: AD[19] = high level H'B: AD[27] = high level
H'4: AD[20] = high level H'C: AD[28] = high level
H'5: AD[21] = high level H'D: AD[29] = high level
H'6: AD[22] = high level H'E: AD[30] = high level
H'7: AD[23] = high level H'F: AD[31] = high level
Other than above AD[31:16] lines are driven to high
level.
10 to 8 FN
Undefined SH: R/W Function Number
PCI:  Specify the function number for a configuration
access. The function numbers ranging from 0 to 7 are
represented in three bits.
7 to 2 CRA
Undefined SH: R/W Configuration Register Address
PCI:  Specify the register for a configuration access at a
longword boundary.

All 0
SH: R Reserved
PCI:  These bits are always read as 0. The write value
should always be 0.
