17.1.4.1 Master Mode
17.1.4.2 Slave Mode
Master mode is entered when the DINC bit in the UiSMR3 register (i = 0 to 4) is set to 1. The following pins are
used in master mode.
To use the SS function, set the SSE bit in the UiSMR3 register to 1. A transmit and receive operation is
performed while an “H” is applied to the SSi pin. If an “L” is applied to the SSi pin, the ERR bit in the UiSMR3
register becomes 1 (mode error occurred) and pins CLKi and TXDi are placed in high-impedance states. Set the
UiIRS bit in the UiC1 register to 1 (Transmit completion as interrupt source) to verify whether a mode error has
occurred or not by checking the EER bit in the transmission complete interrupt routine. To resume serial
communication after a mode error occurs, set the ERR bit to 0 (no mode error) while an “H” signal is applied to
the SSi pin. Pins TXDi and CLKi become in output mode.
Slave mode is entered when the DINC bit in the UiSMR3 register is set to 0. The following pins are used in
slave mode.
To use the SS function, set the SSE bit in the UiSMR3 register to 1. When an “L” signal is applied to the SSi
input pin, the serial clock input is enabled, and a transmit and receive operation becomes available. When an
“H” signal is applied to the SSi pin, the serial clock input to the CLKi pin is ignored and the STXDi pin is
placed in a high-impedance state.
