SINx
This pin is used to input serial data to the device, regardless of the transfer mode.
SOUTx
This pin is used to output serial data from the device, regardless of the transfer mode.
#SCLKx (clock input/output pin) This pin is used to input or output a clock.
In the
In the asynchronous mode, this pin is used as clock input when an external clock is used. This pin is not used when the internal clock is used, so it can be used as an I/O port.
#SRDYx
This pin is used to input or output the ready signal that is used in the
In the
This pin is not used in the asynchronous mode, so it can be used as an I/O port.
