Register 5: ADC Overflow Status (ADCOSTAT), offset 0x010
This register indicates overflow conditions in the sample sequencer FIFOs. Once the overflow
condition has been handled by software, the condition can be cleared by writing a 1 to the
corresponding bit position.

Reset Description
RO 0x0000.000 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 Overflow
When set, this bit specifies that the FIFO for Sample Sequencer 3 has
hit an overflow condition where the FIFO is full and a write was
requested. When an overflow is detected, the most recent write is
dropped.
This bit is cleared by writing a 1.

SS2 FIFO Overflow
When set, this bit specifies that the FIFO for Sample Sequencer 2 has
hit an overflow condition where the FIFO is full and a write was
requested. When an overflow is detected, the most recent write is
dropped.
This bit is cleared by writing a 1.

SS1 FIFO Overflow
When set, this bit specifies that the FIFO for Sample Sequencer 1 has
hit an overflow condition where the FIFO is full and a write was
requested. When an overflow is detected, the most recent write is
dropped.
This bit is cleared by writing a 1.

SS0 FIFO Overflow
When set, this bit specifies that the FIFO for Sample Sequencer 0 has
hit an overflow condition where the FIFO is full and a write was
requested. When an overflow is detected, the most recent write is
dropped.
This bit is cleared by writing a 1.
