Description
Device ID (R: default 789xh). Unique PCT789T-A ID number. The last three bits
of the ID are loaded into this register through three strapped input pins, IDID[2:0],
during the power-on reset period.
Vendor ID (R: default 134Dh). Specifies the manufacturer of the PCT789T-A:

PERR
Description
Detected parity error (R/W: default 0b). Set when the PCT789T-A detects a par-
ity error.
Signaled system error (R/W: default 0b). Set when the PCT789T-A asserts
SERR#.
Reserved. Read returns zero.
DEVSEL timing (R: default 01b). Indicates the timing of the assertion of the
DEVSEL* pin. The PCT789T-A is set for median speed PCI device.
Reserved. Read returns zero.
Capabilities (R: default 1b). When set, indicates that the PCT789T-A is capable
of handling PCI power management.
Reserved. Read returns zero.
System error enable (R/W: default 0b). When set, enables the SERR# driver on
the PCT789T-A to report a system error.
Reserved. Read returns one.
Parity error response (R/W: default 0b). When set, signals the PCT789T-A to
assert PERR* after a parity error detection. Otherwise, any parity error detection
is ignored. Parity checking is disabled after reset.
Reserved. Read returns zero.
I/O space access (W). Set to allow the PCT789T-A to respond to I/O space
accesses.
