3.10.1 LPSPI timing parameters

All LPSPI interfaces do not have the same maximum serial clock frequency. There are

two groups. LPSPI interfaces which can operate at 60 MHz in Master mode and 40

MHz in Slave mode and the other group where interfaces operate at 40 MHz in Master

mode and 20 MHz in Slave mode. The same performance is achieved at 1.8 V and 3.3

V unless otherwise stated.

Below are the LPSPI interfaces and their respective chip selects:

60 MHz in Master mode and 40 MHz in

Slave mode

SPI0, SPI2, SPI3

40 MHz in Master mode and 20 MHz in

Slave mode

SPI1

3.10.1.1 LPSPI Master mode

Waveform is assuming LPSPI is configured in mode 0, i.e. TCR.CPOL=0b0 and

TCR.CPHA=0b0. Timing parameters are valid for all modes using appropriate edge of

the clock.
