When the ACS_REGEN bit in the host interface is set HIGH, the GS1582 will use the
Audio Channel Status information programmed in the ACSR[183:0] register to replace
the Audio Channel Status block in all eight channels. The CRC for the Audio Channel
Status block will be calculated automatically. The GS1582 will use this new Audio
Channel Status information only when ACS_APPLY is HIGH and a new status boundary
at this point. When the ACS_APPLY is set, the APPLY_WAITA host interface bit will be
asserted until a status boundary for audio group 1 occurs. Similarly, APPLY_WAITB will
be asserted starting when ACS_APPLY is set, and ending when a status boundary for
audio group 2 occurs.
Table 4-16 shows the default settings for the Audio Channel Status block. The GS1582
automatically generates the CRC byte.
