89 / 143 page  12 Communication interfaces 12.1 LPSPI The Low Power Serial Peripheral Interface (LPSPI) provides a synchronous serial bus with master and slave operations. Many of the transfer attributes are programmable. The following table provides timing characteristics for classic LPSPI timing modes. 1. All timing is shown with respect to 50% VDD_HV_A/B thresholds. 2. All measurements are with maximum output load of 30pF (except 50pF support on K3x8 with Fast/Medium/Standard-Plus IOs), input transition of 1 ns and pad configured DSE = 1, SRC = 0. Table 44.
