Fig. 9 Serial I/O timing (for LSB first)
The serial I/O counter is set to 7 when data is stored in the serial I/O
register. At each falling edge of the transfer clock, serial data is out-
put to S
OUT
. During the rising edge of this clock, data can be input
from S
IN
and the data in the serial I/O register will be shifted 1 bit.
Transfer direction can be selected by bit 5 of serial I/O mode register.
After the transfer clock has counted 8 times, the serial I/O register will
be empty and the transfer clock will remain at a high level. At this time
the interrupt request bit will be set.
External clock- If an external clock is used, the interrupt request will
be sent after the transfer clock has counted 8 times but transfer clock
will not stop.
Due to this reason, the external clock must be controlled from the
outside. The external clock should not exceed 1MHz at a duty cycle
of 50%. The timing diagram is shown in Figure 9. When using an ex-
ternal clock for transfer, the external clock must be held at “H” level
when the serial I/O counter is initialized. When switching between the
internal clock and external clock, the switching must not be per-
formed during transfer. Also, the serial I/O counter must be initialized
after switching.
Notes 1:
On programming, note that the serial I/O counter is set by
writing to the serial I/O register with the bit managing in-
structions as SEB and CLB instructions.
2:
When an external clock is used as the synchronizing clock,
write transmit data to the serial I/O register at “H” of the
transfer clock input level.

Notes 1 : If internal clock is selected, the Sout pin is at high impedance after transfer is completed.
2 : When an external clock is used as the synchronous clock, write the transmit data to the
serial I/O shift register at “H” of the transfer clock input level.
