When the slave’s SS pin is L, the SEI operates as slave.
goes low, output is immediately disabled on the SCLK and MOSI pins if these pins are configured as open-drain
outputs. This causes the SESR<MODF> flag of the master device to be set. This state is called a mode fault. The
mode fault function is provided to prevent damage caused by a collision between drivers that may occur, for
example, when another device on the same bus becomes the master.
The SCLK pin functions as an output pin when SEI is set for master, or as an input pin when SEI is set for
When SEI is set for master, serial clock is output from the SCLK pin to external devices. After the master starts
When SEI is set for slave, the SCLK pin functions as an input pin.
During data transfer between master and slave, device operation is synchronized by the serial clock output
When the SS pin of the slave device is “H”, data is not taken in regardless of whether the serial clock is available.
For both master and slave devices, data is shifted in and out at a rising or falling edge of the serial clock, and
The MISO and MOSI pins are used for serial data transmission/reception. The status of each pin during master
Also, the SCLK, MOSI, and MISO pins can be set for open-drain by the each pin’s input/output control register
The MISO pin of a slave device becomes an output when the SECR<SEE> bit is set to 1 (SEI operation
