The MASTER / SLAVE bit (SPICTL.2) is set and the CLOCK PHASE bit (SPICTL.3) is cleared.

c(SPC)
= SPI clock cycle time = LSPCLK/4 or LSPCLK/(SPIBRR +1)
t
= LSPCLK cycle time
Internal clock prescalers must be adjusted such that the SPI clock speed is limited to the following SPI clock rate:
Master mode transmit 25-MHz MAX, master mode receive 12.5-MHz MAX
Slave mode transmit 12.5-MAX, slave mode receive 12.5-MHz MAX.
The active edge of the SPICLK signal referenced is controlled by the clock polarity bit (SPICCR.6).
