7 / 52 page  7 MB89980 Series s PIN DESCRIPTION (Continued) *1: FPT-64P-M03 *2: FPT-64P-M09 *3: MQP-64C-P01 Pin no. Pin name I/O circuit type Function LQFP*1 QFP*2 MQFP*3 MB89983 MB89P985 MB89PV980 22 23 X0 A Crystal or other resonator connector pins for the main clock The external clock can be connected to X0. When this is done, be sure to leave X1 open. CR oscillation selectability in model with a mask ROM only. 23 24 X1 20 21 MOD0 C A hysteresis input type Memory access mode setting pins Connect directly to VSS. 21 22 MOD1 19 20 RST D Reset I/O pin This pin is an N-ch open-drain output type with a pull- up resistor, and a hysteresis input type. “L” is output from this pin by an internal reset request (optional). The internal circuit is initialized by the input of “L”. 14 to 15 15 to 16 P00/INT20 to P01/INT21 EF General-purpose I/O ports Also serve as an external interrupt 2 input (wake-up function). External interrupt 2 input is hysteresis input. 25 to 30 26 to 31 P02/INT22 to P07/INT27 EF General-purpose I/O ports Also serve as an external interrupt 2 input (wake-up function). External interrupt 2 input is hysteresis input. 31 to 34 32 to 35 P10/INT10 to P13/INT13 EF General-purpose I/O ports Also serve as input for external interrupt 1 input (wake-up function). External interrupt 1 input is hys- teresis input. 35 to 38 36 to 39 P14 to P17 G H General-purpose I/O ports 39 40 P20/EC J K N-ch open-drain general-purpose I/O port Also serve as the external clock input for the 8/16-bit timer/counter. The peripheral is a hysteresis input. 40 41 P21 L M N-ch open-drain general-purpose I/O port 41 42 P22/TO L M N-ch open-drain general-purpose I/O port Also serves as an 8/16-bit timer/counter output. 42 43 P23 L M N-ch open-drain general-purpose I/O port 43 44 P24/RCO L M N-ch open-drain general-purpose I/O port Also serves as Remote control output. 44 to 45 45 to 46 P25 to P26 L M N-ch open-drain general-purpose I/O port 46 47 P27/PWM2 L M N-ch open-drain general-purpose I/O port Also serves as the square wave or PWM wave output for the 8-bit PWM timer 2. |
