2.2.4 Speaker / Headphone Selector (HP_SEL)
The HP_SEL terminal enables the headphone output or the speaker outputs. The headphone output receives
the processed data output from DAP and PWM channels 1 and 2.
In 6-channel configuration this feature does not affect the two lineout channels.
When low, the headphone output is enabled. In this mode the speaker outputs are disabled. When high, the
speaker outputs are enabled and the headphone is disabled.
Changes in the pin logic level results in a state change sequence using soft mute to the hard mute (M) state
for both speaker and headphone followed by a soft unmute.
When HP_SEL is low, the configuration of channels 1 and 2 are defined by the headphone configuration
register. When HP_SEL is high, the channel 1 and 2 configuration registers define the configuration of
channels 1 and 2.
2.2.5 Mute (MUTE)
The mute control provides a noiseless volume ramp to silence. Releasing mute provides a noiseless ramp
to previous volume. The TAS55508 has both a master and individual channel mute commands. A terminal
is also provided for the master MUTE. The low active master Mute I
2
C register and the MUTE terminal are
logically Or’ed together. If either is set to low, a mute on all channels is performed. The master mute command
operates on all channels regardless on whether the system is in six or eight channel configuration.
When MUTE is invoked, the PWM output stops switching and then goes to an idle state.
The master Mute terminal is used to support a variety of other operations in the TAS5028, such as setting the
inter-channel delay, the serial interface format, and the clock rates. A mute command by the master mute
terminal, individual I
2
C mute, the AM interference mute sequence, the bank switch mute sequence, or
automute overrides an unmute command or a volume command. While a mute is active, the commanded
channels will be placed in a mute state. When a channel is unmuted, it goes to the last commanded volume
setting that has been received for that channel.

a reset.
