ZERO FLAG

Zero-Detect Condition

Zero detection for each output channel is independent from the others. If the data for a given channel remains at

a 0 level for 1024 sample periods (or LRCK clock periods), a zero-detect condition exists for that channel.

Zero Output Flags

Given that a zero-detect condition exists for one or more channels, the zero-flag pins for those channels are set

to a logic-1 state. Each channel, ZERO1 through ZERO6 (pins 1 through 6), has zero-flag pins. In addition, all six

zero flags are logically ANDed together, and the result is provided at the ZEROA pin (pin 48), which is set to a

logic-1 state when all channels indicate a zero-detect condition. The zero-flag pins can be used to operate

external mute circuits, or used as status indicators for a microcontroller, audio signal processor, or other digitally

controlled function.

The active polarity of the zero-flag output can be inverted by setting to 1 the ZREV bit of control register 10. The

reset default is active-high output, or ZREV = 0.
