12.4 Communication between two S32K388 devices

S32K388 devices supports fast data sending between two of them. Interface uses is four data lines at frequency of 6.6MHz in one

direction and four data lines at frequency of 6.6MHz in opposite direction. Configuration of LPSPI interface is 4x data lines half

duplex mode. For purpose of this communication LPSPI2, LPSPI5 and set of PINs was designed. Below figure shows diagram of

connection between two S32K388 devices. Left device will use LPSPI2 in Master 4x data line half duplex mode to send data to

LPSPI2 in Slave 4x dataline half duplex mode on second device. Similarly LPSPI5, but for in opposite direction than LPSPI2 do.
