bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15-13

Unimplemented: Read as ‘0’

bit 12

DISSCK: Disable SCKx pin bit (SPI Master modes only)

= Internal SPI clock is disabled, pin functions as I/O

= Internal SPI clock is enabled

bit 11

DISSDO: Disable SDOx pin bit

= SDOx pin is not used by module; pin functions as I/O

= SDOx pin is controlled by the module

bit 10

MODE16: Word/Byte Communication Select bit

= Communication is word-wide (16 bits)

= Communication is byte-wide (8 bits)

bit 9

SMP: SPIx Data Input Sample Phase bit

Master mode:

= Input data sampled at end of data output time

= Input data sampled at middle of data output time

Slave mode:

SMP must be cleared when SPIx is used in Slave mode.

bit 8

CKE: SPIx Clock Edge Select bit(1)

= Serial output data changes on transition from active clock state to Idle clock state (see bit 6)

= Serial output data changes on transition from Idle clock state to active clock state (see bit 6)

bit 7

SSEN: Slave Select Enable bit (Slave mode)(3)

= SSx pin used for Slave mode

= SSx pin not used by module. Pin controlled by port function

bit 6

CKP: Clock Polarity Select bit

= Idle state for clock is a high level; active state is a low level

= Idle state for clock is a low level; active state is a high level

bit 5

MSTEN: Master Mode Enable bit

= Master mode

= Slave mode

Note 1: The CKE bit is not used in the Framed SPI modes. The user should program this bit to ‘0’ for the Framed

SPI modes (FRMEN = 1).

2: Do not set both Primary and Secondary prescalers to a value of 1:1.

3: This bit must be cleared when FRMEN = 1.
