Function
Auxiliary DAC2 Data[9:0] is the 10-bit output
current control word. Magnitude of the auxiliary
DAC current increases with increasing value. Bit 9 is
the MSB and Bit 0 is the LSB.
1: AUX2_N active.
0: source.
1: sink.
1: auxiliary DAC2 off.
Read only. Active high indicates a timing violation
occurred on the input data port. The IRQ is latched.
This bit is cleared when the Interrupt register is read.
Read only. Active high indicates a timing violation
occurred on the SYNC_I input. The IRQ is latched.
This bit is cleared when the Interrupt register is read.
Read only. Indicates the timing error type.
0: hold time violation.
1: setup time violation.
Meaningful when data timing error IRQ is active.
1: data timing error IRQ is enabled.
1: sync timing error IRQ is enabled.
The received SYNC_O signal is looped back to the
SYNC_I signal.
Indicates device hardware revision number.
0: AUX2_P active.
0: auxiliary DAC2 on.
0: data timing error IRQ is masked.
0: sync timing error IRQ is masked.
