16.3.1.4
When a PCI error is detected, the appropriate error bit is set in the PCI error detect register. Subsequent
errors set the appropriate error bits in the error detection registers, but relevant information (attributes,
address, and data) is captured only for the first error. The PCI error detect register is a write-1-to-clear type
register. That is, reading from this register occurs normally; however, write operations are different in that
the bits can be cleared but not set. A bit is cleared whenever the register is written, and the data in the
corresponding bit location is a 1. For example, to clear bit 25 and not affect any other bits in the register,
the value 0x0000_0040 is written to the register.
The error bit is set regardless of the state of the corresponding error enable bit in the PCI error enable
register. The error enable bits are used to send or block the error reporting to the interrupt mechanism. The
interrupt can be cleared by writing 0xFFFF_FFFF to the PCI error detect register.
A master-abort condition during a configuration cycle is not necessarily an error. In this case, if relevant,
the master abort error enable can be disabled to prevent the reporting of master-aborts during outbound
configuration cycles. Master-aborts during configuration reads return 0xFFFF_FFFF.
For an inbound configuration write transaction with a parity error, the device always updates the register
access and generates the error interrupt if the interrupt enabled bit is set.
