The look-up table index is derived from the current temperature measurement as follows:
D[1]
read/write
D[0]
read/write
INDEX = TAVG / 2
where T (n) is the current average temperature. This register allows the current table index to be read by the host. The table
AVG
base address must be added to LUTINDX to form a complete table index in physical memory. A valid OEM password is
required for access to this register. Otherwise, reads are undefined.

This register is non-volatile and will be maintained through power and reset cycles. A valid OEM password is required for
access to this register. GPOD and GPOC are ignored when GPOM = 0. TXFPOL is ignored if TXFIN = 0.

This register reflects (reads back) the value set in the APC register (APCSET0, APCSET1, or APCSET2 whichever is
selected). A valid OEM password is required for access to this register.
