ZFGx: Zero-Detection Flag<br />
Where x = L or R, corresponding to the <strong>DAC</strong> output channel. These bits are available only for readback.<br />
Default value: 00<br />
ZFGx = 0 Not zero<br />
ZFGx = 1 Zero detected<br />
These bits show zero conditions. Their status is the same as that of the zero flags at ZEROL (pin 1) and ZEROR (pin 2).<br />
See Zero Detect in the FUNCTION DESCRIPTIONS section.<br />

R: Read Mode Select<br />
Value is always 1, specifying the readback mode.<br />
ID[4:0]: Device ID<br />
The ID[4:0] bits hold a device ID in the TDMCA mode.<br />
