The MASTER bit (SPInCTRL2.3) is set and the CLOCK PHASE bit (SPInCTRL2.0) is set.
t
= interface clock cycle time = 1/f
For rise and fall timings, see the "Switching Characteristics for Output Timings versus Load Capacitance" table.
When the SPI is in master mode, the following must be true:
For PS values from 1 to 255: t
c(SPC)M
≥
(PS +1)t
c(ICLK)
≥
100 ns, where PS is the prescale value set in the SPInCTL1[12:5] register bits.
For PS values of 0: t
= 2t
≥
100 ns.
The active edge of the SPInCLK signal referenced is controlled by the CLOCK POLARITY bit (SPInCTRL2.1).
The active edge of the SPInCLK signal referenced is controlled by the CLOCK POLARITY bit (SPInCTRL2.1).
