Sample Rate Converter Registers
The sample rate converter (SRC) is composed of five registers which are
described in the following sections.
Control Registers (SRCCTLx)
The SRCCTLn control registers (read/write) control the operating modes,
filters, and data formats used in the sample rate converter. For n = 0, the
register controls the SRC0 and SRC1 modules and for n = 1 it controls the
SRC2 and SRC3 modules (x = 0, 2 and y = 1, 3). The bit settings for these
registers are shown in Figure A-98 and described in Table A-96.
7–4 FIFO_RDI Read Index Pointer. Reflects the read index status during
core reads from the IDP_FIFO.
0000 = No read done
1000 = 8 reads done
31–8 Reserved
