Datasheet
.
When viewed as a 8-bit value, the contents of the
Index
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
‘
0
’
), and when the value of this register is in the
range 40h
–
7Fh, a Socket B register is selected (Socket Index bit is
‘
1
’
). This register only reads
back for Device 0. Device 1 will read back only the upper data byte when 16-bit reads occur at
3E0h.
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:
