Audio Status In 0 and 1
[31:0]
Audio Status In 0 and 1. These registers contain the data
clocked in status words in FrForm one. Frform one clocks
in 16 bits of status data from each audio frame. Status
data from AI_D[0] is loaded into the most significant 16-
bits of the Audio Status In 0 register. Status data from
AI_D[1] is loaded into the least significant 16-bits of the
Audio. Data is captured only when the associated input
DMA is capturing. These registers are typically used to
capture codec status.
Audio Status Out Register
Memory Space Address: 0x050014
Audio Status Out
[31:0]
Audio Status Out. Contains the data clocked in control
words in Frform one. Frform one clocks out 32 bits of data
from AudioStatusOut[1] to the AO_D [3:0] pins during
each audio frame. Data is clocked even when the output
DMA is not active. This register is typically used to control
codec status.
