17.4.5 Corrective Action in Case of Slippage of Serial Clock and Shift Operations
shift operations due to noise, etc. In this case, since the serial clock counter is initialized by disabling both transmit operations
and receive operations (by clearing (0) the CTXE bit and CRXE bit), synchronization of the shift operations and the serial
clock can be restored by using the first serial clock input after reception or transmission is next enabled as the first clock.
17.5 SBI MODE
to the clocked serial I/O method to allow communication with multiple devices using two signal lines. This allows a reduction
in the number of ports used and in the wiring on the board when a serial bus is configured with multiple microcomputers
and peripheral ICs.
When an external clock is selected as the serial clock, there may be slippage between the number of serial clocks and
The SBI (serial bus interface) is a high-speed serial interface system that conforms to the NEC serial bus format.
The SBI is a single-master high-speed serial bus, with a format in which bus configuration functions have been added
Please refer to the Serial Bus Interface (SBI) User’s Manual (EEU-1303) for details of SBI functions, etc.
