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.

Description
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
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 and this
bit is set by hardware to indicate the occurrence of dropped data. This
bit is cleared by writing a 1.
SS2 FIFO Overflow
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 and this
bit is set by hardware to indicate the occurrence of dropped data. This
bit is cleared by writing a 1.
SS1 FIFO Overflow
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 and this
bit is set by hardware to indicate the occurrence of dropped data. This
bit is cleared by writing a 1.
SS0 FIFO Overflow
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 and this
bit is set by hardware to indicate the occurrence of dropped data. This
bit is cleared by writing a 1.
