Register 40h Line 1 DAC/ADC Rate
Reset settings = 0x0000
Each DAC/ADC pair is governed by a read/write modem sample rate control register that contains a 16-bit
unsigned value between 0 and 65535, representing the rate of operation in Hz. A number written over 0x3592 will
cause the sample rate to be 13.714 kHz. For all rates, if the value written to the register is supported, that value will
be echoed back when read, otherwise the closest rate supported is returned.
When set to zero, the internal PLL is disabled. The PLL should be programmed before the line side (Si3014) is
activated via clearing any PR bit in register 3Eh. Furthermore, sleep mode is not supported when the PLL is
disabled.
