Input/Output Pins

Table 16.1 shows the pin configuration. This module automatically switches the input/output direction of the SSL pin.
SSL is set as an output in master mode and as an input in slave mode. Pins RSPCK, MOSI, and MISO are automatically
set as inputs or outputs according to the setting of master or slave and the level input on SSL (see section 16.4.2, Pin
Control).
