SF0BRR is a special function register (SFR) used to set the operation mode.
Do not change the setting of this register during transfer. Operation is not guaranteed if it is changed during
transfer.

[Note]
The maximum SSIOF transfer frequency is 4MHz. This setting should not exceed 4MHz.
If using P22 as SCKF0 in master mode, the max frequency is 2MHz.
•
SF0LEAD1-0
(bits 13 to 12)
SF0LEAD1-0 set the SSF0 –SCKF0 delay interval (setting enabled only in Master mode).
