To generate the internal clock synchronized with the external clock, set the SU1HIM bit in the UiSMR2
register (i=0 to 4) and the SCLKDIV bit in the UiSMR register to values shown in Table 16.29. Then apply
a trigger signal to the CTSi pin. Either the same clock cycle as the external clock or external clock divided
by two can be selected as the transfer clock. The SCLKSTPB bit in the UiC1 register controls the transfer
clock. Set the SCLKSTPB bit accordingly, to start or stop the transfer clock during an external clock
operation. Figure 16.27 shows an example of the clock-divided synchronous function.
