The PCI arbiter interrupt mask register (PCIAINTM) sets interrupt masks for the individual
interrupts that occur due to errors generated during PCI transfers performed by other PCI devices
when the PCIC is operating as the host with the arbitration function. Each bit is set to 0 to disable
the respective interrupt, or 1 to enable that interrupt.
The PCIINTM register is initialized to H'00000000 at a power-on reset or software reset.
Bits 31 to 14—Reserved: These bits always return 0 when read. Always write 0 to these bits
when writing.
Bit 13—Master Broken Interrupt Mask (MST_BRKN)
Bit 12—Target Bus Timeout Interrupt Mask (TGT_BUSTO)
