CONTROL REGISTER MAP
(Software Mode Only)
The control register map for the SRC4184 is shown in Table 7. There are two identical register banks, one for SRC A and
one for SRC B, each conforming to the register map shown in Table 7.
Register 0 is reserved for factory use and defaults to all zeros upon reset. The user should avoid writing to or reading this
register, as unexpected operation may result if Register 0 is programmed to an arbitrary value.
Register 1 through Register 5 contain control bits, which are programmed to configure specific internal functions.
Register 1 through Register 5 are available for write or read access. Register 6 and Register 7 contain the integer and
fractional parts of the f

sampling ratio and are read only status registers.
