Master Mode Clock Frequency
Section 35. Serial Peripheral Interface (SPI) (Part II)
In the Master mode, the clock provided to the SPI1 module is the instruction cycle (T
clock will then be prescaled by the primary prescaler, specified by PPRE<1:0>
(SPI1CON1<1:0>), and the secondary prescaler, specified by SPRE<2:0> (SPI1CON1<4:2>).
The prescaled instruction clock becomes the serial clock and is provided to external devices
through the SCK1 pin.
Equation 35-1 can be used to calculate the SCK1 clock frequency as a function of the primary
and secondary prescaler settings.
Equation 35-1:
Some sample SPI clock frequencies (in kHz) are shown in Table 35-1.

Note that the SCK1 signal clock is not free running for normal SPI modes. It will only
run for 8 or 16 pulses when the SPI1BUF is loaded with data. However, it is
continuous for Framed modes.
Not all clock rates are supported. For further information, refer to the SPI module
timing specifications in the specific device data sheet.
