Bits Mnemonic Type Reset Description

|
31:6 R 0 .times. 0 Reserved
|
|
5 SCRESET RW 0 .times. 0 Sample Counter Reset: When a `1` is
|
|
written to this
|
|
bit the AISLRCNT register is rest to 0
|
|
.times. 0O.
|
|
Read:
|
|
always 0
|
|
Write:
|
|
0 = No effect
|
|
1 = Reset AISLRCNT register
|
|
4 AIINTVLD RW 0 .times. 0 Audio Interface Interrupt Valid.
|
|
This bit controls
|
|
whether AIINT is affected by the AIIT
|
|
register
|
|
matching AISLRCNT. Once set, AIINT will
|
|
hold its
|
|
last value.
|
|
0 = March affects AIINT.
|
|
1 = AIINT hold last value.
|
|
3 AIINT RW 0 .times. 0 Audio Interface Interrupt Status
|
|
and clear. On read
|
|
this bit indicates the current status of
|
|
the audio
|
|
interface interrupt. When a `1` is
|
|
written to this
|
|
register, the interrupt is cleared. This
|
|
interrupt
|
|
indicates that the AIIT register matches
|
|
the
|
|
AISLRCNT. This bit asserts regardless of
|
|
the setting
|
|
of AICR[AIMSK].
|
|
Write:
|
|
0 = No effect
|
|
1 = Clear Audio Interface interrupt
|
|
Read:
|
|
0 = Audio Interface Interrupt has not
|
|
been
|
|
requested
|
|
1 = Audio Interface Interrupt has been
|
|
requested.
|
|
2 AIINTMSK RW 0 .times. 0 Audio interface Interrupt Mask:
|
|
0 = interrupt masked
|
|
1 = Interrupt enabled
|
|
1 AFR RW 0 .times. 0 Auxiliary Frequency Register:
|
|
Controls the sample
|
|
rate of the streaming audio data. When
|
|
set to 32 kHz
|
|
sample rate, the SRC will convert the
|
|
streaming
|
|
audio data to 48 kHz. This bit should
|
|
only be
|
|
changed when Streaming Audio is stopped
|
|
(AICR[PSTAT] set to 0).
|
|
0 = 32 kHz sample rate
|
|
1 = 48 kHz sample rate
|
|
0 PSTAT RW 0 .times. 0 Playing Status: This bit enables
|
|
the AISLR clock
|
|
which controls the playing/stopping of
|
|
audio
|
|
streaming. When this bit is AISLRCNT
|
|
register will
|
|
increment for every stereo pair of
|
|
samples output.
|
|
0 = Stop or Pause streaming audio (AISLR
|
|
clock
|
|
disabled)
|
|
1 = Play streaming audio (AISLR clock
|
|
enabled)

|
is issued when the value of the
