EC2OS DATA EC-REGISTER BYTE 0

EC2OS_DATA_ECREG_B0

; ALIAS=OS_DATA_B0

This register is aliased; see ACPI-OS DATA BYTES[3:0] on page 177, OS2EC DATA BYTES[3:0] on page 184, and

EC2OS DATA BYTES[3:0] on page 186 for detailed description of access rules.

EC2OS DATA BYTES[3:0]

Writes by the ACPI_EC to the EC2OS DATA BYTES[3:0] are aliased to the ACPI-OS DATA BYTES[3:0]

All access to the EC2OS DATA BYTES[3:0] registers should be orderly: Least Significant Byte to Most Significant Byte

when byte access is used.

When the Four Byte Access bit in the Byte Control OS-Register is cleared to ‘0’, the following access rules apply:

Writes to the EC2OS Data EC-Register Byte 0 set the OBF bit in the STATUS OS-Register.

Reads from the EC2OS DATA BYTES[3:0] have no effect on the IBF bit in the STATUS OS-Register.

All reads from EC2OS DATA BYTES[3:1] return 00h without error.

All writes to EC2OS DATA BYTES[3:1] complete without error but the data are not registered.

Access to EC2OS DATA BYTES[3:1] have no effect on the IBF & OBF bits in the STATUS OS-Register.

When the Four Byte Access bit in the Byte Control OS-Register is set to ‘1’, the following access rules apply:

Writes to the EC2OS Data EC-Register Byte 3 set the OBF bit in the STATUS OS-Register.

Reads from the EC2OS DATA BYTES[3:0] have no effect on the IBF bit in the STATUS OS-Register.

EC2OS DATA EC-REGISTER BYTE 1

EC2OS_DATA_ECREG_B1

; ALIAS=OS_DATA_B1

This register is aliased; see ACPI-OS DATA BYTES[3:0] on page 177, OS2EC DATA BYTES[3:0] on page 184, and

EC2OS DATA BYTES[3:0] on page 186 for detailed description of access rules.
