Datasheet
When viewed as a 7-bit value, the contents of this register completely specify a single internal-
register byte. For example, when the value of this register is in the range 00h–3Fh, a Socket A
register is selected (Socket Index bit is a ‘0’), and when the value of this register is in the range
40h–7Fh, a Socket B register is selected (Socket Index bit is a ‘1’).
The internal register that is accessed when the CPU reads or writes the Data register is determined
by the current value of the Index register, as follows:

NOTES:
1. This register affects both sockets (it is not specific to either socket).
2. This register is only applicable for the extended index 6F register.
3. This register is only applicable for the extended index 2F register.
