separated with a slash (/).
(2) PULL column:
IPD = Internal Pulldown resistor
IPU = Internal Pullup resistor
(3) If the GPIO column is 'Y', then in GPIO mode, the pin is configurable as an IO unless otherwise marked.

remain in a high impedance state as long as the part is in power-down mode. The Mute Control pin goes
to the selected "active" state during reset, muting, or if the master clock to left/right clock frequency ratio
is incorrect. This pin is intended to be used as a control for external mute circuits to prevent the clicks
and pops that can occur in any single supply system. The use of external mute circuits are not mandatoy but may be desired for designs requiring the absolute minimum in extraneous clicks and pops.
