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
Reserved bits return an indeterminate value, and should
never be changed.
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.
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.
