12.10 Audio Sample Rate Control register (index 0x2C and 0x32)
The sample rate control registers contain 16-bit unsigned values between 0 and
65535, representing the rate of operation in Hz.
Table 31
shows the sample rates
supported by UCB1400.
In VRA mode (VRA = 1 in register 0x2A), if the value written to the register is
supported, that value will be echoed back when read, otherwise the closest (higher in
case of a tie) sample rate supported is returned. The UCB1400’s DAC and ADC are
capable of operating at independent rates.
In non-VRA mode (VRA = 0 in register 0x2A), the only supported sample rate is
48 kHz.
