Status Register 2 (STAT2)

The Status Register 2 holds status information related to the 8HP I/O expansion module and
the rear I/O expansion module.
Table 4-11: Status Register 2 (STAT2)
REGISTER NAME
ADDRESS
BIT NAME
7 - 6 Res. Reserved
5 - 4 RCFG Rear I/O configuration:
00 = Rear I/O disabled (CP308 front I/O version with 64-bit termina-
01 = COM1, GPIO
10 = Reserved
11 = COM1, COM2
The default value depends on the CP308 version ordered (front I/O
or rear I/O) and the rear I/O Module used.
3 - 2 GCFG 8HP graphics expansion configuration:
00 = PCI Express Graphics port implementation on 8HP graphics
01 = 8HP GMCH graphics expansion with implemented HDA audio
10 = 8HP GMCH graphics expansion without implemented HDA
11 = No 8HP graphics expansion present (onboard pull-up resistors)
The default value depends on the 8HP graphics expansion used.
1 - 0 IOCFG 8HP I/O expansion configuration:
00 = 8HP I/O expansion does not use any PCI Express interface
01 = 8HP I/O expansion needs one x4 PCI Express configuration
10 = 8HP I/O expansion needs four x1 PCI Express configuration
11 = No 8HP I/O expansion present (onboard pull-up resistors)
The default value depends on the 8HP I/O expansion used.
