(a) INTP3, INTP5
These are external interrupt request input pins for which the valid edge (rising edge, falling edge, or both rising and
falling edges) can be specified.
(b) RTC1HZ
This is a real-time clock correction clock (1 Hz) output pin.
(c) TXD0, TXD1
These are serial data output pins of the UART0 and UART1 serial interface.
(d) RXD0, RXD1
These are serial data input pins of the UART0 and UART1 serial interface.
(e) SCK00, SCK01, SCK10
These are serial clock I/O pins of the CSI00, CSI01, and CSI10 serial interface.
(f) SI00, SI01, SI10
These are serial data input pins of the CSI00, CSI01, and CSI10 serial interface.
(g) SO00, SO10
These are serial data output pins of the CSI00 and CSI10 serial interface.
(h) TI00, TI02, TI04 to TI06, TI11 to TI13
These are pins for inputting an external count clock/capture trigger to 16-bit timers.
(i) TO00, TO02, TO04 to TO06, TO11 to TO13
These are timer output pins of 16-bit timers.
(j) SDA00, SDA01, SDA10
These are serial data I/O pins of the simplified I
2
C serial interface.
(k) SCL00, SCL01, SCL10
These are serial clock I/O pins of the simplified I
2
C serial interface.
(l) TRDIOA0, TRDIOB0, TRDIOC0, TRDIOD0, TRDIOA1, TRDIOB1, TRDIOC1
These are timer I/O pins of timer RD.
(m) TRDCLK0
This is an external clock input pin of timer RD.
(n) TRJO0
This is a timer output pin of timer RJ.
(o) LTXD0, LTXD1
These are serial data output pins for the LIN. LTXD1 is provided only in the 100-pin products of RL78/F14.
(p) LRXD0, LRXD1
These are serial data input pins for the LIN. LRXD1 is provided only in the 100-pin products of RL78/F14.
