SLES090A—November 2003—Revised January 2004
TAS5076
Because PDN is an asynchronous control signal, small clicks and pops can be produced during the application
(the leading edge) of this control. However, when PDN is released, the transition from the hard mute state back
to normal operation is performed synchronously using a quiet sequence.
If a completely quiet reset sequence is desired, MUTE must be applied before applying PDN.
2.2.3 General Status Register
The general status register is a read-only register. This register provides an indication when a volume update
is in progress or one of the channels is inactive. The device ID can be read using this register.
Volume update is in progress—Whenever a volume change is in progress due to a volume update
command or mute, this status bit is high.
Device identification code—The device identification code 0 0000 is displayed.
No internal errors (all valid signals are high)—When there are no internal errors in the TAS5076 and all
outputs are valid, this status bit is high.
One or more valid signals are inactive—If low, one or more channels of the TAS5076 are not outputting data.
The valid signals for those channels are inactive.
Inactive valid signals can be produced by one of these causes:
One or more of the clock signals are in error.
ERROR recover is active (low).
The automute has silenced one or more channels that are receiving 0 inputs.
MUTE has been set.
Volume control has been set to full attenuation.
If this signal is high, the TAS5076 is outputting data on all channels.
2.2.4 Error Status Register
The error status register indicates historical information on control signal changes and clock errors. This
register latches these indications when they occur. The indications are cleared by writing 00h to the register.
This register is intended as a diagnostic tool to be used only when the system is not operating correctly. This
is because the error status bits are set when the data rate, serial data interface format, or master/slave mode
is changed. As a result, this register indicates an error condition even though the system is operating normally.
This register must be used only while diagnosing transient error conditions.
Any clock error or control signal terminal change that occurs since the last time the error status register was
cleared is displayed. In using this register, the first step is to initialize the device and verify that all of the clock
signals are active. Then this register must be cleared by writing 00h. After this point, the register indicates any
errors or control signal changes.
This register indicates an error condition by a high for the following conditions:
Fs error
A control terminal change has occurred (M_S, DBLSPD).
LRCLK error
MCLK_IN count error
DCLK phase error with respect to MCLK_IN
MCLK_IN phase error with respect to DCLK
PWM timing error
If all bits of the register are low, no errors have occurred and no control terminals changed.
There is no one-to-one correspondence of clock error indication to a system error condition. A particular
system error can be indicated by one or more error indications in this register. The system error conditions
and the reported errors are as follows:
There is no correct number of MCLKs per LRCLK:
Fs error has occurred.
LRCLK error
MCLK_IN count error
