12 / 80 page  µPD78P324, 78P324(A) 12 (2) Pins other than ports (1/2) I/O Output Input Input Input Input Output Input Output I/O I/O I/O Output Output Output Output Function Real-time output port performing pulse outputs synchro- nously with the trigger symbols from the real-time pulse unit (RPU). External interrupt request input of edge detection. A valid edge can be selected by the external interrupt mode register. Non-maskable interrupt request input of edge detection. A valid edge can be selected by the external interrupt mode register. External counter clock input to Timer 1 (TM1). Serial data input of the asynchronous serial interface (UART). Serial data output of the asynchronous serial interface (UART). Serial data input in three-wire mode of the clock synchro- nous serial interface. Serial data input in three-wire mode of the clock synchro- nous serial interface. Serial data output in three-wire mode of the clock synchronous serial interface. Serial clock I/O of the clock synchronous serial interface. Address data bus for accessing external memory. Address bus for accessing external memory. Read signal output to external memory. Write signal output to external memory. Control signal output for accessing the turbo access manager ( µPD71P301)Note. Output from the real-time pulse unit.
