Function
AUX DAC2 10-bit output current control word.
Magnitude of the AUX DAC current increases with
increasing value. Bit 9 is the MSB and Bit 0 is the LSB.
0: AUX2_P active
1: AUX2_N active
0: source
1: sink
0: AUX DAC2 on
1: AUX 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.
0: Data Timing Error IRQ is masked
1: Data Timing Error IRQ is enabled
0: Sync Timing Error IRQ is masked
1: Sync Timing Error IRQ is enabled
The received SYNC_I signal is looped back to the
SYNC_O output pins.
Indicates device hardware revision number.
