EQADC_CF[0–5]R
n
provide visibility of the contents of a CFIFO for debugging purposes. Each CFIFO
has four registers that are uniquely mapped to its four 32-bit entries. Refer to
,” for more information on CFIFOs. These registers are read only. Data written to these
registers is ignored.

Explanation
IDLE
0b00
• CFIFO is disabled.
• CFIFO is in single-scan edge or level trigger mode and does not have EQADC_FISRn[SSS]
asserted.
• eQADC completed the transfer of the last entry of the user defined command queue in
single-scan mode.
Reserved

Not applicable.
WAITING
FOR
TRIGGER
0b10
• CFIFO mode is modified to continuous-scan edge or level trigger mode.
• CFIFO mode is modified to single-scan edge or level trigger mode and EQADC_FISRn[SSS]
is asserted.
• CFIFO mode is modified to single-scan software trigger mode and EQADC_FISRn[SSS] is
negated.
• CFIFO is paused.
• eQADC transferred the last entry of the queue in continuous-scan edge trigger mode.
