22. PCI Controller (PCIC)
Bit 13—Master Broken Interrupt Mask (MST_BRKN)
Bit 12—Target Bus Timeout Interrupt Mask (TGT_BUSTO)
Bit 11—Master Bus Timeout Interrupt Mask (MST_BUSTO)
Bits 10 to 4—Reserved: These bits always return 0 when read. Always write 0 to these bits when
writing.

The PCI error bus master data register (PCIBMLR) stores the device number of the bus master at
the time an error occurred in PCI transfer by another PCI device when the PCIC was operating as
the host with the arbitration function. It is a 32-bit register than can be read from both the PP bus
and PCI bus.
The PCIINTM register is initialized to H'00000000 at a power-on reset or software reset. A valid
value is retained only when one of the PCIAINT register bits is set to 1.
