LQFP*
67
PA3
E
This is a general-purpose I/O port.
SID2
This is a data input pin of I/O simple serial interface 2.
Because this input is used as required when is performing input
operations, and it is I/O simple serial interface 2 necessarey to stop
outputs by other functions unless such outputs are made
intentionally.
68
PA4
E
This is a general-purpose I/O port.
This function becomes valid when data output from I/O simple
serial interface 2 is disabled.
SOD2
This is a data output pin of I/O simple serial interface 2.
This function becomes valid when data output from I/O simple
serial interface 2 is enabled.
69
PA5
E
This is a general-purpose I/O port.
This function becomes valid when clock output from I/O simple
serial interface 2 is disabled.
SCK2
This is clock output pin of I/O simple serial interface 2.
This function becomes valid when clock output from I/O simple
serial interface 2 is enabled.
