Description

. Clock Rate (REG4 bit(2))
  . The clock rate (MCLK) must be set before using functionality of the MX93000C
  . Programmable clock rate :
       1. 2.048MHz (Frame Sync. 8KHz)
       2. 1.536MHz (Frame Sync. 8KHz)
. Data Format (REG4 bit(1,0))
  . The data format must be set before using functionality of the MX93000C
  . Programmable Data Format
      1. 16-bit linear data format (it can get 14-bit resolution and higher linearity than that of u/a-law data format)
      2. 8-bit u-law data format
      3. 8-bit a-law data format
