3.
The set clock is used w hen the internal clock is selected.
The SSCK pin functions as the transfer clock output pin w hen the MSS bit is set to 1 (operates as master device).
The MSS bit is set to 0 (operates as slave device) w hen the CE bit in the SSSR register is set to 1 (conflict error
occurs).
The RSSTP bit is disabled w hen the MSS bit is set to 0 (operates as slave device).
