Fig. 11. Structure of serial I/O mode register
Internal clock—the serial I/O counter is set to “7” during write cycle
into the serial I/O register (address 021416), and transfer clock goes
“H” forcibly. At each falling edge of the transfer clock after the write
cycle, serial data is output from the SOUT pin. Transfer direction can
be selected by bit 5 of the serial I/O mode register. At each rising
edge of the transfer clock, data is input from the SIN pin and data in
the serial I/O register is shifted 1 bit.
After the transfer clock has counted 8 times, the serial I/O counter
becomes “0” and the transfer clock stops at “H.” At this time the inter-
rupt request bit is set to “1.”
External clock—when an external clock is selected as the clock
source, the interrupt request is set to “1” after the transfer clock has
counted 8 times. However, transfer operation does not stop, so con-
trol the clock externally. Use the external clock of 500kHz or less
with a duty cycle of 50%.
The serial I/O timing is shown in Figure 10. When using an external
clock for transfer, the external clock must be held at “H” for initializing
the serial I/O counter. When switching between an internal clock and
an external clock, do not switch during transfer. Also, be sure to ini-
tialize the serial I/O counter 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.
