and RJ16 mode.
// AD1896, DIR, DIT, AD1852 MCLK control logic. Based on the Master/Slave operation of the
AD1896 in/out ports,
// 33.8688MHz crystal frequency will be divided by either 1, 2 or 3 and the ouput of the di-
vider is feed into the DAC and DIT.
// On-board 12.288MHz clock oscillator is enabled only when input and ouput serial ports are
configured in SLAVE mode.
// IO control logic for bi-directional signals
// AD1896 ASRC Output Serial port signals
// DAC AND DIT SIGNALS
// Internal node signals
