eQADC CFIFO Control Registers 0–5 (EQADC_CFCRn)
The eQADC_CFCRs contain bits that affect CFIFOs. These bits specify the CFIFO operation mode and
can invalidate all of the CFIFO contents.

RF_POPn
[0:15]
Result FIFO pop data n. When RFIFOn is not empty, the RF_POPn contains the next
unread entry value of RFIFOn.
Reading the whole word, a halfword, or any bytes of
EQADC_RFPRn will pop one entry from RFIFOn, and the corresponding RFCTRn value
will be decremented by 1 (See Section 19.3.2.8). When the RFIFOn is empty, any read
on EQADC_RFPRn returns undefined data value and does not decrement the RFCTRn
value. Writing to EQADC_RFPRn has no effect.

SSEn
CFIFO single-scan enable bit n. Used to set the SSSn bit, as described in Section 19.3.2.8.
Writing a 1 to SSEn will set the SSSn if the CFIFO is in single-scan mode. When SSSn is
already asserted, writing a 1 to SSEn has no effect. If the CFIFO is in continuous-scan
mode or is disabled, writing a 1 to SSEn will not set SSSn. Writing a 0 to SSEn has no
effect. SSEn always is read as 0.
0 No effect.
1 Set the SSSn bit.
