28.2.2 Output Data Register (SRCOD)
SRCOD is a 32-bit read-only register used to output the data after sampling rate conversion. The
data in the output data FIFO is read through SRCOD. When the number of data in the output data
FIFO is zero after the start of conversion, the value previously read is read again.
(1) Output Data Register_0 (SRCOD_0)

(2) Output Data Register_1 (SRCOD_1)
The conversion result is stored in bits 31 to 16. Bits 15 to 0 are always read as 0.
