In order for the AC ’97 Digital Controller to access the UCB1400, the 2-bit Codec ID
field (chip select) (LSBs of Output Slot 0) must be set to ‘0’ (see
Table 4
). The
UCB1400 shall monitor the Frame Valid, Slot 1 Valid Command Address, Slot 2 Valid
Command Data and Codec ID bits, and respond only if properly accessed by the
AC ’97 Digital Controller, as illustrated in
Table 5
. Note that although SLOTREQ bits
reside in slot 1, they have validity independent of the tag bit for Valid Slot 1 Address.
The UCB1400 shall only set SDATA_IN tag bits for Slot 1 (Address) and Slot 2 (Data)
to ‘1’ when returning valid data from a previous register read, regardless of the
validity of SLOTREQ bits (see also
Section 8.5
).
