Bit 29 — Received Master Abort
Bit 30 — Received System Error (SERR#)
Bit 31 — Address/Data Parity Error Detected
56
To clear this bit, software must write a ‘1’ to it.
This bit is set whenever the CardBus interface detects an address parity error. Bit 17 of the
Interrupt Line, Interrupt Pin, and Bridge Control register (memory offset 3Ch) must be set
before system errors can be reported, and bit 16 of the Interrupt Line, Interrupt Pin, and Bridge
Control register must be set to allow address parity errors to be detected. The CL-PD6833 only
asserts SERR# if address parity errors occur. To clear this bit, software must write a ‘1’ to it.
This bit indicates whether a parity error was detected, independent of whether bit 16 of the Bridge
Control register (memory offset 3Ch) is ‘1’. To clear this bit, software must write a ‘1’ to it.
