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.
ADC Overflow Status (ADCOSTAT)

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
Value Description
1 The FIFO for Sample Sequencer 3 has hit an overflow condition,
meaning that the FIFO is full and a write was requested. When
an overflow is detected, the most recent write is dropped.
0 The FIFO has not overflowed.
This bit is cleared by writing a 1.
