18.3.7
The DCI module has a dedicated 12-bit time base that
produces the bit clock. The bit clock rate (period) is set
by writing a non-zero 12-bit value to the BCG<11:0>
control bits in the DCICON3 SFR.
When the BCG<11:0> bits are set to zero, the bit clock
will be disabled. If the BCG<11:0> bits are set to a non-
zero value, the bit clock generator is enabled. These
bits should be set to ‘0’ and the CSCKD bit set to ‘1’ if
the serial clock for the DCI is received from an external
device.
The formula for the bit clock frequency is given in
Equation 18-2.

EQUATION 18-2:
The required bit clock frequency will be determined by
the system sampling rate and frame size. Typical bit
clock frequencies range from 16x to 512x, the con-
verter sample rate depending on the data converter
and the communication protocol that is used.
To achieve bit clock frequencies associated with com-
mon audio sampling rates, the user will need to select
a crystal frequency that has an ‘even’ binary value.
Examples of such crystal frequencies are listed in
Table 18-1.
