Figure 15.40 SOUT3’s Initial Value Setting
15.2.3 Functions for Setting SOUT3 Initial Value
If the SM36 bit in the S3C register is set to 0 (external clock), the SOUT3 pin output can be fixed high or
low when not transferring. However, the last bit value of the former data is retained between data and
data when transmitting the continuous data.
Figure 15.40 shows the timing chart and how to set it for the SOUT3’s Initial Value Setting.
(Example) When "H" selected for SOUT3 initial value
* This diagram applies to the case where the bits in the S3C register are set as follows:

1.If the SM36 bit = 1 (internal clock) or if the SM32 bit = 1 (SOUT3 output disabled), this output
2.SOUT3 can only be initialized when input on the CLK3 pin is in the high state if the SM34 bit in

goes to the high-impedance state.
the S3C register = 0 (transmit data output at the falling edge of the transfer clock) or in the low
state if the SM34 bit = 1 (transmit data output at the rising edge of the transfer clock).
SM32 = 0 (SOUTi output)
SM35 = 0 (LSB first)
SM36 = 0 (external clock)
