22. PCI Controller (PCIC)
Always write to this register prior to accessing the PCI configuration space. After setting a value
in this register, generate the configuration cycle by reading or writing to the PIO data register
(PCIPDR).
Also, a special cycle is issued by setting H'8000FF00 in this register and writing to the PCIPDR.
Bit 31—Configuration Cycle Generate Enable (CFGEN): Indicates the configuration cycle
generation enable.
Bits 30 to 24—Reserved: These bits always return 0 when read. Always write 0 to these bits
when writing.
Bits 23 to 16—PCI Bus No. (BUSNO): These bits specify the No. of the PCI bus subject to
configuration access. Bus No. D indicates the bus connected with the PCIC. The bus No. is
expressed with 8 bits, and its maximum value is 255.
Bits 15 to 11—Device No. (DEVNO): These bits specify the No. of the device subject to
configuration access. The device No. is expressed with 5 bits, and takes a value from bits 0 to 31.
In place of IDSEL, one of bits 31 to 16 of the A/D line, corresponding to the device No. set in this
field, is driven to “1”. The following table shows the relationship between the device No. and
IDSEL (A/D [31 to 16]). When the device No. is 10h or greater, A/D [31 to 16]) are all zeros.

H'3
Bits 10 to 8: Function No. (FNCNO): These bits specify the No. of the function subject to
configuration access. The function No. is expressed with 3 bits, and takes a value of 0 to 7.
Bits 7 to 2—Configuration Register Address (REGADR): These bits set the register subject to
configuration access with a longword boundary.
Bits 1 and 0—Reserved: These bits always return 0 when read. Always write 0 to these bits when
writing.
