Register 7: ADC Underflow Status (ADCUSTAT), offset 0x018
This register indicates underflow conditions in the sample sequencer FIFOs. The corresponding
underflow condition is cleared by writing a 1 to the relevant bit position.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

SS3 FIFO Underflow
When set, this bit specifies that the FIFO for Sample Sequencer 3 has
hit an underflow condition where the FIFO is empty and a read was
requested. The problematic read does not move the FIFO pointers, and
0s are returned.
This bit is cleared by writing a 1.

SS2 FIFO Underflow
When set, this bit specifies that the FIFO for Sample Sequencer 2 has
hit an underflow condition where the FIFO is empty and a read was
requested. The problematic read does not move the FIFO pointers, and
0s are returned.
This bit is cleared by writing a 1.

SS1 FIFO Underflow
When set, this bit specifies that the FIFO for Sample Sequencer 1 has
hit an underflow condition where the FIFO is empty and a read was
requested. The problematic read does not move the FIFO pointers, and
0s are returned.
This bit is cleared by writing a 1.

SS0 FIFO Underflow
When set, this bit specifies that the FIFO for Sample Sequencer 0 has
hit an underflow condition where the FIFO is empty and a read was
requested. The problematic read does not move the FIFO pointers, and
0s are returned.
This bit is cleared by writing a 1.
