NOTE: The serial port interface always gluelessly works with the DSP. The following modes will not produce
50% duty cycle SCLK:
1. If the number of devices in cascade >4 and N is an odd number (i.e., N = 1, 3, 5,...)
2. If the number of devices in cascade
≤4, FIR is bypassed, and N ≠ 4, 8, 12, 16, 20, 24, 28, 32
