Prescaler divide factor. PRESDIV determines the ratio between the system clock frequency
and the serial clock (S-clock). The S-clock is determined by the following calculation:
The reset value of PRESDIV is 0x00, which forces the S-clock to default to the same
frequency as the system clock. The valid programmed values are 0 through 255.

Resynchronization jump width. The RJW field defines the maximum number of time quanta
a bit time may be changed during resynchronization. The valid programmed values are zero
through three.
The resynchronization jump width is calculated as follows:
PSEG1[2:0] — Phase buffer segment 1. The PSEG1 field defines the length of phase buffer
segment one in the bit time. The valid programmed values are zero through seven.
The length of phase buffer segment 1 is calculated as follows:
PSEG2 — Phase Buffer Segment 2. The PSEG2 field defines the length of phase buffer
segment two in the bit time. The valid programmed values are zero through seven.
The length of phase buffer segment two is calculated as follows:
2
Resynchronizaton Jump Width = (RJW + 1) Time Quanta
Phase Buffer Segment 1 = (PSEG1 + 1) Time Quanta
Phase Buffer Segment 2 = (PSEG2 + 1) Time Quanta
