× 256. In this configuration, two consecutive primary communications represent the
same data sample.

FIR Bypass Mode
An option is provided to bypass the FIR sections of the decimation filter and the interpolation filter. This is
selected through the control 2 register. The sinc filters of the two paths cannot be bypassed.
The timing requirements for this mode of operation are shown in Figure 3 –7.

NOTE A: The number of clocks between primary cycles is a function of FCLK. When either FIR is bypassed, this period
is 16 FCLKs. See Fk divide register in Appendix A.
