29 / 210 page ![]() RL78/F23, F24 2. PIN FUNCTIONS R01DS0446EJ0120 Rev.1.20 Page 29 of 207 Dec 31, 2025 (2/2) Function Name I/O Function After Reset Alternate Function P70 I/O Port 7 Input of P70, P71, and P73 can be set to TTL input buffer. P70 to P74 can be set to analog input. Use of an on-chip pull-up resistor can be specified by a software setting. Output from P70 to P72 can be set to N-ch open-drain output. For input to P70, P71, P73, and P75 to P77, the threshold level can be specified. Analog input port ANI26/KR0/INTP8/SI11/SDA11/ SNZOUT4 P71 ANI27/KR1/INTP6/SCK11/SCL11/ SNZOUT5 P72 ANI28/KR2/SO11/SNZOUT6 P73 ANI29/KR3/SSI11/SNZOUT7 P74 ANI30/KR4/(SO10)/(TXD1) P75 Input port KR5/(SI10)/(RXD1) P76 KR6/(SCK10) P77 KR7/(SSI10)/INTP12 P80 I/O Port 8 P80 to P87 can be set to analog input. Analog input port ANI0 P81 ANI1 P82 ANI2 P83 ANI3 P84 ANI4 P85 ANI5 P86 ANI8 P87 ANI9 P90 I/O Port 9 P90 to P97 can be set to analog input. Analog input port ANI10 P91 ANI11 P92 ANI12 P93 ANI13 P94 ANI14 P95 ANI15 P96 ANI16 P97 ANI17 P120 I/O Port 12 Input of P125 can be set to TTL input buffer. P120 and P125 can be set to analog input. For P120, P125, and P126, use of an on-chip pull-up resistor can be specified by a software setting. Output from P120 can be set to N-ch open-drain output. For input to P120 and P125, the threshold level can be specified. Analog input port ANI25/TI07/TO07/TRDIOD0/ SO01/(SCK10)/INTP4 P121 Input Input port X1 P122 X2/EXCLK P123 XT1 P124 XT2/EXCLKS P125 I/O Analog input port ANI24/TI03/TO03/TRDIOB0/ SSI01/INTP1/SNZOUT1 P126 Input port (TI01)/(TO01) P130 Output Port 13 Output port RESOUT P137 Input Input port INTP0 P140 I/O Port 14 Use of an on-chip pull-up resistor can be specified by a software setting. Input port TRD1RES/PCLBUZ0 Remark Functions in parentheses in the above table can be assigned via settings in the peripheral I/O redirection registers (PIORx). |
