2.0 Device Architecture and Configuration
2.10.7 SuperI/O Configuration 6 Register (SIOCF6)
Write access to this register can be inhibited by setting bit 7. Activation of each logical device (bits 0-4) is also affected by
bit 0 of the logical device Activate register, index 30h and bit 0 of the SIOCF1 register.
Location:
Type:
2.10.8 SuperI/O Revision ID Register (SRID)
This register contains the ID number of the specific family member (Chip ID) and the chip revision number (Chip Rev). The
Chip Rev field identity number the chip revision.
