SERR

 

 

PCI System Error. This bit is set when the PCI SERR∗

 

 

 

 

 

 

 

 

 

 

pin is asserted. The bit may be cleared by writing it to a 1;

 

 

 

 

 

 

 

 

 

 

writing it to a 0 has no effect. When the SERRM bit in the

 

 

 

 

 

 

 

 

 

 

MEREN register is set, the assertion of this bit will assert

 

 

 

 

 

 

 

 

 

 

MCHK to the master designated by the DFLT bit in the

 

 

 

 

 

 

 

 

 

 

 

MERAT register. When the SERRI bit in the MEREN

 

 

 

 

 

 

 

 

 

 

 

register is set, the assertion of this bit will assert an

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

interrupt through the MPIC interrupt controller.

 

 

 

 

 

 

 

 

 

 

 

SMA

 

 

PCI Master Signalled Master Abort. This bit is set

 

 

 

 

 

 

 

 

 

 

 

 

 

when the PCI master signals master abort to terminate a

 

 

 

 

 

 

 

 

 

 

 

PCI transaction. The bit may be cleared by writing it to a

 

 

 

 

 

 

 

 

 

 

1; writing it to a 0 has no effect. When the SMAM bit in

 

 

 

 

 

 

 

 

 

 

the MEREN register is set, the assertion of this bit will

 

 

 

 

 

 

 

 

 

 

 

assert MCHK to the master designated by the MID field

 

 

 

 

 

 

 

 

 

 

in the MERAT register. When the SMAI bit in the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

MEREN register is set, the assertion of this bit will assert

 

 

 

 

 

 

 

 

 

 

an interrupt through the MPIC interrupt controller.

 

 

 

 

 

 

 

 

 

RTA

 

 

PCI Master Received Target Abort. This bit is set when

 

 

 

 

 

 

 

 

 

 

the PCI master receives target abort to terminate a PCI

 

 

 

 

 

 

 

 

 

 

 

transaction. The bit may be cleared by writing it to a 1;

 

 

 

 

 

 

 

 

 

 

 

writing it to a 0 has no effect. When the RTAM bit in the

 

 

 

 

 

 

 

 

 

 

MEREN register is set, the assertion of this bit will assert

 

 

 

 

 

 

 

 

 

 

MCHK to the master designated by the MID field in the

 

 

 

 

 

 

 

 

 

 

MERAT register. When the RTAI bit in the MEREN

 

 

 

 

 

 

 

 

 

 

 

 

 

register is set, the assertion of this bit will assert an

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

interrupt through the MPIC interrupt controller.
