Figure 26.13
26.5.4
When the SSUMS bit in the SSMR2 register is set to 1 (4-wire bus communication mode) and the CSS1 bit is
set to 1 (function as the SCS output pin), set the MSS bit in the SSCRH register to 1 (operation as the master
device) and check the arbitration of the SCS pin before starting serial transfer. If the synchronous serial
communication unit detects that the synchronized internal SCS signal is held low in this period, the CE bit in
the SSSR register is set to 1 (conflict error) and the MSS bit is automatically set to 0 (operation as a slave
device).
Figure 26.13 shows the Arbitration Check Timing.
Future transmit operations are not performed while the CE bit is set to 1. Set the CE bit to 0 (no conflict error)
before starting transmission.
