25.5.2.6 EQADC Result FIFO Pop Registers (EQADC_RFPR)
The EQADC Result FIFO Pop Registers (EQADC_RFPR) provide a mechanism to retrieve data from
RFIFOs.

Field Description
0-31
CF_PUSHx
[0:31]
CFIFO Push Data x
When CFIFOx is not full, writing to the whole word or any bytes of EQADC_CFPRx will push
the 32-bit CF_PUSHx value into CFIFOx. Writing to the CF_PUSHx field also increments the
corresponding CFCTRx value by one in
Section 25.5.2.9, EQADC FIFO and Interrupt Status
Registers (EQADC_FISR) . When the CFIFOx is full, the EQADC ignores any write to the
CF_PUSHx. Reading the EQADC_CFPRx always returns zero.
Note: Only whole words must be written to EQADC_CFPR. Writing half-words or bytes to
EQADC_CFPR will still push the whole 32-bit CF_PUSH field into the corresponding
CFIFO, but undefined data will fill the areas of CF_PUSH that were not specifically
designated as target locations for the write.
