RL78/D1A CHAPTER 2 PIN FUNCTIONS
(2) Control mode
P131 to P137 function as timer I/O, output pins for the sound generator, serial interface data I/O, external interrupt
request input, and segment signal outputs for the LCD controller/driver.
(a) TI00 (P136), TI20 (P132), TI21 (P131), TI22 (P133), TI24 (P134), and TI26 (P135)
These are the pins for inputting an external count clock/capture trigger to 16-bit timers00, 20, 21, 22, 24, and 26.
(b) TO00 (P136), TO20 (P132), TO21 (P131), TO22 (P133), TO24 (P134), and TO26 (P135)
These are the timer output pins of 16-bit timers00, 20, 21, 22, 24, and 26.
(c) SGO (P135)
This is the output pin for the sound generator.
(d) SGOA (P134)
This is the amplitude PWM output pin for the sound generator.
(e) SGOF (P135)
This is the frequency output pin for the sound generator.
(f) SO10 (P131)
This is a serial data output pin of serial interface CSI10.
(g) SI10 (P132)
This is a serial data input pin of serial interface CSI10.
(h) SCK10 (P133)
This is a serial clock I/O pin of serial interface CSI10.
(i) LTxD1 (P131)
This is a Serial data output from LIN-UART.
(j) LRxD0 (P132)
This is a Serial data input to LIN-UART.
(k) SCL11 (P136)
This is a serial clock output pin of serial interface for simplified I2C.
(l) CTxD1 (P134) (R5F10DPJxFB only)
This is a CAN serial transmit data output pin of aFCAN1.
(m) CRxD1 (P135) (R5F10DPJxFB only)
This is a CAN serial receive data input pin of aFCAN1.
(n) INTP5 (P137)
This is an external interrupt request input pin for which the valid edge (rising edge, falling edge, or both rising and
falling edges) can be specified.
(o) INTPLR1 (P132)
This is an external interrupt request input for which the valid edge for LIN-UART1.
(p) SEG48 (P136)
This is a segment signal output pin for the LCD controller/driver.
