Pin 25
Pin 26
Pin 27 has chip select (CS) function for R-IN32M3-EC Clocked Serial Interface H 1 (CSIH1) which works in Slave Mode at CSIHTCSS1 channel 1. The used chip select sink for this (SPI_RST1) is used as reset input for the Clocked Serial Interface H 1 and is internally connected to R-IN32M3-EC based module is Port P72P75.Pin 4 connect the RESETZ ball
Pin 24 (SPI_SCK1) complies the SCK function for SPI connection. This channel 1 CSIHTSCK signal connect the serial clock of R-IN32M3-EC . So an external reset signal can initialize the CPU core and the internal peripheral modules.Pin 5 complies the MISO at Port P35. For interrupts and peripheral modulessee also User’s Manual R18UZ0007EJ1100 chapter 17 Clocked Serial Interface H (CSIH)
Pin 25 (SPI_MOSI1) complies the MOSI function for SPI connection. This pin connect the R-IN32M3-EC CSIH serial data output input signal at Port P47 P36 (CSISO0CSISI1).
Pin 626 (SPI_MISO1) complies the MOSI MISO function for SPI connection. This pin connect the R-IN32M3-EC CSIH serial data input output signal at Port P46 P37 (CSISI0CSISO1).Pin 7 complies the SCK function for SPI connection. This channel 0 CSIH signal connect the serial clock of
Pin 27 (SPI_CS1) has chip select (CS) function for R-IN32M3-EC Clocked Serial Interface H 1 (CSIH1) which works in Slave Mode at CSIHTCSS1 channel 1. The used chip select sink for this R-IN32M3-EC at based module is Port P45P72.
