Lower output level to
maximum attenuation
Mute the speaker output
Set D/C low
Codec programmed for
Master mode & ITS=0
Set external controller to
drive SCLK and FSYNC
into the codec
Send valid control information
with CLB=0
Read back and verify control information.
Mask off reserved bits
n = 5
Send valid control information
with CLB=0
n = n - 1
CLB=0
Set CLB=1 and send at least
two more frames of valid
control information
2
Set external controller to
receive SCLK and FSYNC
from the codec
Is codec
programmed for
Master mode
Set D/C high.
Transmit/receive data with attenuated outputs
and muted speaker for 194 FSYNC cycles
while codec executes offset calibration
Transmit/receive audio data
with desired level settings
n = 0
Poll for CLB=0

Wait at least 12 SCLK
periods for FSYNC and
SCLK to three-state
This is a software design choice,
not a run-time conditional branch.

This will cause the codec to
ignore any further bus activity.
The SDOUT pin will be held in
the high impedance state after
transmitting 1 frame with CLB=1
