Bus collision detection (SIO1)
SIO1 can detect a bus collision by setting UART1 bus collision de-
tection interrupt enable bit.
When transmission is started in the clock synchronous or asyn-
chronous (UART) serial I/O mode, the transmit pin TxD1 is
compared with the receive pin RxD1 in synchronization with rising
edge of transmit shift clock. If they do not coincide with each other,
a bus collision detection interrupt request occurs.
When a transmit data collision is detected between LSB and MSB
of transmit data in the clock synchronous serial I/O mode or be-
tween the start bit and stop bit of transmit data in UART mode, a
bus collision detection can be performed by both the internal clock
and the external clock.
A block diagram is shown in Fig. 54.
A timing diagram is shown in Fig. 55.
Note: Bus collision detection can be used when SIO1 is operating
at full-duplex communication. When SIO1 is operating at
half-duplex communication, set bus collision detection inter-
rupt to be disabled.
