26
26
Interrupt Output; an open drain output indicating that a set EOM bit
has been found during Playback, or that the chip is in an Overflow
(OVF) condition. This pin remains LOW until a Read Status
command is executed.
MCLK

27
This pin allows the internal clock of the Voice record/playback
system to be externally driven for enhanced timing precision. This
pin is grounded for most applications. It is required for the CODEC
operation.
SCL
