Description
Clock Rate Select. This pin is used to select between an MCLK of 256
512
Data Format Select 0. This pin is used as the low bit (DF0) of the data format selection
(see section on External Control).
Data Format Select 1. This pin is used as the high bit (DF1) of the data format selection
(see section on External Control).
Master/Slave Select. This pin is used to select between the Master (pin low) or Slave (pin
high) Modes.
Description
This pin provides a clock output that allows the user to decode the left and right channel
modulator outputs. It is similar to a left/right clock but runs (nominally) at 5.6448 MHz
and gates a 4-bit modulator output word in each phase (see section on Modulator Mode).
