Functions for setting an SOUTi initial value
When using an external clock for the transfer clock, the SOUTi pin output level during a non-transfer
time can be set to the high or the low state. Figure 1.19.31 shows the timing chart for setting at SOUTi
initial value and how to set it.

(Example) With “H” selected for SOUTi:
Note: The set value is output only when the external clock has been selected.
When initializing SOUTi, make sure the CLKi pin input is held “L” level.
If the internal clock has been selected or if SOUT output disable has been
set, this output goes to the high-impedance state.

Note 1: With the internal clock selected for the transfer clock, the frequency dividing ratio can be selected using
bits 0 and 1 of the S I/Oi control register. (No frequency division, 8-division frequency, 32-division frequency.)
Note 2: With the internal clock selected for the transfer clock, the SOUTi terminal becomes to the high-impedance
state after the transfer finishes.
Note 3: In M30623(80-pin package), the input pin SIN3 of S I/O3 is not connected to external pin.
Note 4: Shown above is the case where the SOUTi (i = 3, 4) port select bit = “1”.
