Register 20: ADC Sample Sequence FIFO 3 Status (ADCSSFSTAT3), offset
0x0AC
This register provides a window into the sample sequencer, providing full/empty status information
as well as the positions of the head and tail pointers. The reset value of 0x100 indicates an empty
FIFO. The ADCSSFSTAT0 register provides status on FIFO0, ADCSSFSTAT1 on FIFO1,
ADCSSFSTAT2 on FIFO2, and ADCSSFSTAT3 on FIFO3.

DescriptionResetTypeNameBit/Field
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.

FIFO Full
When set, this bit indicates that the FIFO is currently full.
