Table 16 Processing sequence of data transfer from master to slave
1-byte data is serially transferred on this process. Subsequently, data
can be transferred continuously by repeating the process from *.
When an external clock is selected as a synchronous clock, the
clock is not controlled internally. Control the clock externally be-
cause serial transmit/receive is performed as long as clock is
externally input. (Unlike an internal clock, an external clock is not
stopped when serial transfer is completed.) However, the SIOF flag
is set to “1” when the clock is counted 8 times after executing the
SST instruction. Be sure to set the initial level of the external clock
to “H.”
Master (transmission)
[Initial setting]
Setting the serial I/O mode register J1 and inter-
rupt control register V2 shown in Figure 40.
TJ1A and TV2A instructions
Setting the port received the reception enable
signal (SRDY) to the input mode.
(Port D3 is used in this example)
SD instruction
* [Transmission enable state]
Storing transmission data to serial I/O register SI.
TSIAB instruction
[Transmission]
Check port D3 is “L” level.
SZD instruction
Serial transfer starts.
SST instruction
Check transmission completes.
SNZSI instruction
Wait (timing when continuously transferring)
Slave (reception)
[Initial setting]
Setting serial I/O mode register J1, and interrupt control register V2 shown in
Figure 40.
TJ1A and TV2A instructions
Setting the port transmitted the reception enable signal (SRDY) and outputting
“H” level (reception impossible).
(Port D3 is used in this example)
SD instruction
*[Reception enable state]
The SIOF flag is cleared to “0.”
SST instruction
“L” level (reception possible) is output from port D3.
RD instruction
[Reception]
Check reception completes.
SNZSI instruction
“H” level is output from port D3.
SD instruction
[Data processing]
