141 / 456 page  2014 - 2015 Microchip Technology Inc. DS00001719D-page 141 MEC1322 10.13.1 OS2EC DATA EC BYTE 0 REGISTER This register is aliased; see ACPI-OS DATA BYTES[3:0] on page 135, OS2EC DATA BYTES[3:0] on page 141, and EC2OS DATA BYTES[3:0] on page 142 for detailed description of access rules. OS2EC DATA BYTES[3:0] When the CMD bit in the OS STATUS OS Register is cleared to ‘0’, reads by the ACPI_EC from the OS2EC DATA BYTES[3:0] are aliased to the ACPI-OS DATA BYTES[3:0]. All access to the OS2EC 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 OS Byte Control Register is cleared to ‘0’, the following access rules apply: 1. Writes to the OS2EC DATA BYTES[3:0] have no effect on the OBF bit in the OS STATUS OS Register. 2. Reads from the OS2EC Data EC Byte 0 Register clears the IBF bit in the OS STATUS OS Register. 3. All reads from OS2EC DATA BYTES[3:1] return 00h without error. 4. Access to OS2EC DATA BYTES[3:1 has no effect on the IBF & OBF bits in the OS STATUS OS Register. When the FOUR_BYTE_ACCESS bit in the OS Byte Control Register is set to ‘1’, the following access rules apply: 1. Writes to the OS2EC DATA BYTES[3:0] have no effect on the OBF bit in the OS STATUS OS Register. 2. Reads from the OS2EC Data EC Byte 3 Register clears the IBF bit in the OS STATUS OS Register. 10.13.2 OS2EC DATA EC BYTE 1 REGISTER This register is aliased; see ACPI-OS DATA BYTES[3:0] on page 135, OS2EC DATA BYTES[3:0] on page 141, and EC2OS DATA BYTES[3:0] on page 142 for detailed description of access rules. 107h Reserved 108h OS2EC Data EC Byte 0 Register 109h OS2EC Data EC Byte 1 Register 10Ah OS2EC Data EC Byte 2 Register 10Bh OS2EC Data EC Byte 3 Register Offset 108h Bits Description Type Default Reset Event 7:0 OS_TO_EC_DATA_BYTE_0 This is byte 0 of the 32-bit OS2EC DATA BYTES[3:0]. R/W 0h VCC1_R ESET Offset 109h Bits Description Type Default Reset Event 7:0 OS2EC_DATA_ BYTE_1 This is byte 1 of the 32-bit OS2EC DATA BYTES[3:0].
