Section 19 Synchronous Serial Communication Unit (SSU)
19.4.4
The SSU switches the input/output pin (SSI, SSO, SSCK, and SCS) functions according to the
communication modes and register settings. When a pin is used as an input pin, clear the
corresponding bit in each data direction register (DDR) to 0. The relationship of communication
modes and input/output pin functions are shown in tables 19.4 to 19.6.
