Register:
Command
Type:
Read only, read/write (see individual bit descriptions)
Offset:
04h
Default:
0000h
Description: The command register provides control over the PCI1221 interface to the PCI bus. All bit
functions adhere to the definitions in PCI Local Bus Specification 2.2. None of the bit functions
in this register are shared between the two PCI1221 PCI functions. Two command registers
exist in the PCI1221, one for each function. Software must manipulate the two PCI1221
functions as separate entities when enabling functionality through the command register. The
SERR_EN and PERR_EN enable bits in this register are internally wired-OR between the two
functions, and these control bits appear separately according to their software function. See
Table 16 for the complete description of the register contents.
