8 / 106 page MB90520 Series 8 s PIN DESCRIPTION Pin no. Pin name Circuit type Function LQFP-120*1 QFP-120*2 92, 93 X0, X1 A This is a high-speed crystal oscillator pin. 74, 73 X0A, X1A B This is a low-speed crystal oscillator pin. 89 to 87 MD0 to MD2 C This is an input pin for selecting operation modes. Connect directly to VCC or VSS. 90 RST C This is an external reset request signal input pin. 86 HST C This is a hardware stand-by input pin. 95 to 101 P00 to P06 D This is a general-purpose I/O port. This function can be set by the port 0 input pull-up resistor setup register (RDR0) for input. For output, however, this function is invalid. INT0 to INT6 This is a request input pin of the DTP/external interrupt circuit ch.0 to ch.6. 102 P07 D This is a general-purpose I/O port. This function can be set by the port 0 input pull-up resistor setup register (RDR0) for input. For output, however, this function is invalid. 103 to 110 P10 to 17 D This is a general-purpose I/O port. This function can be set by the port 1 input pull-up resistor setup register (RDR1) for input. For output, however, this function is invalid. WI0 to WI7 This is an I/O pin for wake-up interrupts. 111, 112, 113, 114 P20, P21, P22, P23 E This is a general-purpose I/O port. IC00, IC01, IC10, IC11 This is a trigger input pin for input capture (ICU) 0 and 1. Since this input is used as required for input capture 0 and 1 (ICU) ch.0, ch.01, ch.10 and ch.11 input operation, output by other functions must be suspended except for intentional operation. 115 P24 E This is a general-purpose I/O port. AIN0 This port can be used as count clock A input for 8/16-bit up/down counter/timer 0. 116 P25 E This is a general-purpose I/O port. BIN0 This port can be used as count clock B input for 8/16-bit up/down counter/timer 0. *1: FPT-120P-M05 *2: FPT-120P-M13 (Continued) |
