Extended Audio ID Register (Index 28h)
ID[1:0]
Codec ID. These bits indicate the current codec configuration. When ID[1:0] = 00, the
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.
AMAP
Audio Slot Mapping. The AMAP bit indicates whether the optional AC ’97 2.1 compliant
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-
VRM
Variable Rate Mic Audio. The VRM bit indicates whether variable rate Mic audio is supported.
This bit always returns ‘1’, indicating that variable rate mic audio is available.
VRA
Variable Rate PCM Audio. The VRA bit indicates whether variable rate PCM audio is support-
ed. This bit always returns ‘1’, indicating that variable rate PCM audio is available.
Default
x209h. The Extended Audio ID Register (Index 28h) is a read-only register.
