Description
Normal Chain Complete (Default: 0x0)
1: Indicates that the Chain transfer ended in the Normal state.
0: Indicates that Chain transfer has not ended since this bit was previously
cleared.
Normal Data Transfer Complete (Default: 0x0)
1: Indicates that the data transfer specified by the PDMAC Register ended in
the Normal state.
0: Indicates that data transfer has not ended since this bit was previously
cleared.
Configuration Error (Default: 0x0)
1: Indicates that either the current setting of the control portion in the Control
Register and the Address/Count Register are not consistent with each other
or the PDMAC stipulation is not being obeyed. DMA transfer stops.
0: Indicates that the current setting of the control portion in the Control
Register can be tolerated.
PCI Fatal Error (Default: 0x0)
1: Indicates that an error was signaled on the PCI Bus during the Chain
process.
0: Indicates that no error has been signaled on the PCI Bus since this bit was
previously cleared.
1: Indicates that a G-Bus error occurrred during the Chain process. DMA
transfer stops.
0: Indicates that no G-Bus error has occurred during the Chain process since
this bit was cleared.
G-Bus Data Bus Error (Default: 0x0)
1: Indicates that a G-Bus error occurred during the data transfer process.
DMA transfer stops.
0: Indicates that no G-Bus error has occurred during the data transfer process
since this bit was cleared.
