bit 4-2 SPRE<2:0>: Secondary Prescale bits (Master mode)
(3)
111 = Secondary prescale 1:1
110 = Secondary prescale 2:1

000 = Secondary prescale 8:1
bit 1-0 PPRE<1:0>: Primary Prescale bits (Master mode)
(3)
11 = Primary prescale 1:1
10 = Primary prescale 4:1
01 = Primary prescale 16:1
00 = Primary prescale 64:1
REGISTER 18-2: SPIXCON1: SPIX CONTROL REGISTER 1 (CONTINUED)
Note 1: The CKE bit is not used in the Framed SPI modes. Program this bit to ‘0’ for Framed SPI modes
(FRMEN = 1).
2: This bit must be cleared when FRMEN = 1.
3: Do not set both Primary and Secondary prescalers to a value of 1:1.
4: The SMP bit must be set only after setting the MSTEN bit. The SMP bit remains cleared if MSTEN = 0.
