CS4205 is the primary audio codec. When ID[1:0] = 01, 10, or 11, the CS4205 is a secondary
audio codec. The state of the ID[1:0] bits is determined at power-up from the ID[1:0]# pins
and the current clocking scheme, see Table 27 on page 63.
AC-link slot to audio DAC mapping is supported. This bit is a shadow of the AMAP bit in the
AC Mode Control Register (Index 5Eh). The PCM playback and capture slots are mapped ac-
cording to Table 14 on page 43.
This bit always returns ‘1’, indicating that variable rate mic audio is available.
