Note: 32h is an alias for 78h. The VRA bit in register 2Ah must be set for the alias to work; if a zero is written to VRA, both
sample rates are reset to 48 kHz.
SR0[15:0]
Writing to this register allows the user to program the sampling frequency from 7 kHz (1B58h) to 48 kHz (BB80h)
in 1 Hertz increments. Programming a value greater than 48 kHz or less than 7 kHz may cause unpredictable
results.
