<Synchronous Normal Slave Mode (SCI1 only)>

The receive operation starts when SR1REN of SR1CON is set to "1" by the program.
SR1FREE, that indicates receiving, becomes "L" level, and the receive shift clock to
input to the RXC1 pin is accepted (refer to Figure 15-35).

The receive shift clock detects the edge synchronizing with the CLK to generate
SR1CLK.

Receive data is controlled synchronizing with SR1CLK.

If the RXC1 pin becomes "L" level, and then becomes "H" level, the receive shift clock
SR1CLK is generated by the edge detection circuit.

If SR1CLK is generated, the receive data just sampled the RXD1 pin is shifted in the
receive register.

The RXD1 pin is sampled while the RXC1 pin is in "L" level. The timing to shift in the
receive register occurs after the RXC1 pin rises. Therefore the transmit side transmits
data synchronizing with the fall of the RXC1 pin, which is the fall of the transmit shift
clock.

Hereafter, receive data is shifted in the receive register sequentially, synchronizing with
the receive shift clock, which is input according to the specification of SR1CON.

If the receive shift clock finally rises, SR1CLK acquired by edge detection is generated,
and the final receive data is input. Then 1 CLK later, the receive end signal LSR1BUF is
generated.

If LSR1BUF is generated, the content of the receive register (receive data) is trans-
ferred to S1BUF, an overrun error and parity error (if parity bit exists) are set, the
receive interrupt request signal (RX1READY) is generated, synchronizing with the
M1S1 signal that indicates the beginning of an instruction, and the interrupt request flag
(QSCI1) is set to "1". Then SR1FREE becomes "H" level. At this time SR1REN of
SR1CON does not become "L" level, and the receive operation starts again if the next
receive shift clock is input.

<Synchronous Multiprocessor Communication Slave Mode (SCI1 only)>

In synchronous multiprocessor communication slave mode, receive is controlled by the
same timing as synchronous normal slave mode. The differences are shown below.

• Setting of multiprocessor communication error

• If SR1MPC of SR1CON is "0", receive data is accepted regardless of the MPC bit of

receive data. When SR1MPC of SR1CON is "1", receive data is accepted if the MPC
bit of receive data is "1", but receive data is not accepted if the MPC bit of receive
data is "0". This means that data shifted in the shift register will not be loaded to
S1BUF, and also that an interrupt request will not be generated.
