Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
31:12 | 0h | RO | Reserved (RSVD_0)
|
11:10 | 0h | RO | Power Well (PW) Indicates the power well. |
9:5 | 0h | RW/O | Number of Output Expanders (NOUT) BIOS programs this field to indicate number of output expander components which corresponds to multiple of CxGPO in byte granularity. This field is 1-based ('00001' means 1 output expander which produces 8 bits of CxGPO). |
4:0 | 0h | RW/O | Number of Input Expanders (NIN) BIOS programs this field to indicate number of input expander components which corresponds to multiple of CxGPO. This field is 1-based ('00001' means 1 input expander which produces 8 bits of CxGPI). |
