Section 16 Synchronous Serial Communication Unit (SSU)
16.4.6
When bits CSS1 and CSS0 in SSCRH are specified to B'10 and the SSUMS bit in SSCRL is
cleared to 0, the SCS pin functions as an input (Hi-Z) to detect a conflict error. A conflict error
detection period is from setting the MSS bit in SSCRH to 1 to starting serial transfer and after
transfer ends. When a low level signal is input to the SCS pin within the period, a conflict error
occurs. At this time, the CE bit in SSSR is set to 1 and the MSS bit is cleared to 0.
Note: While the CE bit is set to 1, transmission or reception is not resumed. Clear the CE bit to 0
