Master Loopback mode: In this mode LPSPI_SCK clock is delayed for sampling the input data which is enabled by setting LPSPI_CFGR1[SAMPLE] bit as 1. 5. These specifications apply to the SPI operation, as master or slave, at up to 10 Mbps for the combinations not indicated in the table below. Unless otherwise noted, all other ‘master’ and ‘slave’ specifications are also applicable in the 10Mbps configurations. See table "LPSPI 20 MHz and 15 MHz Combinations. 6. LPSPI0 support up to 20MHz on fast pin. 7. Minimum configuration value for CR[PCSSCK] field is 3(0x00000011). 8. Minimum configuration value for CCR[SCKPCS] field is 3(0x00000011). 9. While selecting odd dividers, ensure Duty Cycle is meeting this parameter. fperiph = LPSPI peripheral clock MSB OUT2 LSB OUT BIT 6 ... 1 MSB IN2 SS1 (OUTPUT) SPSCK (CPOL = 0) (OUTPUT) SPSCK (CPOL = 1) (OUTPUT) MISO (INPUT) MOSI (OUTPUT) LSB IN BIT 6 ... 1 3 5 5 7 10 11 6 12 13 12 13 4 2 Figure 38.
