ACPI REGISTERS

The ACPI registers are organized in three groups, all of which are VSB powered. The offsets are related to the base address

determined by the Base Address registers at indexes 62h - 67h in the SWC device configuration.

The PC8741x devices support the following ACPI fixed register groups:

• PM1 Event Group (block b), containing the PM1b_STS and PM1b_EN registers, each with a length of two bytes.

• PM1 Control Group (block b), containing the PM1b_CNT register with a length of 2 bytes.

• General-Purpose Event 1 Group, containing the GPE1_STS and GPE1_EN registers, each with a length of four bytes.

The following abbreviations are used to indicate the Register Type:

R/W

= Read/Write.

= Read from a speciﬁc register (write to the same address is to a different register).

= Write (see above).

= Read Only.

= Write Only. Reading from the bit returns 0.

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.
