(1)

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

(2)

c(SPC)

= SPI clock cycle time = LSPCLK/4 or LSPCLK/( 1)

(3)

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 MHz MAX, slave mode receive 12.5 MHz MAX.

(4)

c(LCO)

= LSPCLK cycle time

(5)

The active edge of the SPICLK signal referenced is controlled by the CLOCK POLARITY bit (SPICCR.6).
