3.6

The following abbreviations are used to indicate the Register Type:

R/W

= Read/Write.

= Read from a speciﬁc address returns the value of a speciﬁc register. Write to the same address is to a dif-

ferent register.

= Write.

= Read Only.

R/W1C = Read/Write 1 to Clear. Writing 1 to a bit clears it to 0. Writing 0 has no effect.

R/W1S = Read/Write 1 to Set. Writing 1 to a bit sets its value to 1. Writing 0 has no effect.

SUPERI/O CONFIGURATION REGISTERS

This section describes the SuperI/O configuration and ID registers (those registers with first level indexes in the range of

20h-2Eh). See Table 14 for a summary and directory of these registers.

Note: Set the conﬁguration registers to enable functions or signals that are relevant to the speciﬁc device. The values of

ﬁelds that select functions, or signals, that are excluded from a speciﬁc device are treated as reserved and should

not be selected.
