9 / 52 page  9 MB89150/150A Series s PIN DESCRIPTION (Continued) *1: FPT-80P-M11 *2: FPT-80P-M06 *3: FPT-80P-M05 *4: MQP-80C-P01 Pin no. Pin name Circuit type Function LQFP*1*3 MQFP*4 QFP*2 16 18 X0 A Main clock oscillator pins 15 17 X1 18 20 MOD0 C Operating mode selection pins Connect directly to VSS. 17 19 MOD1 19 21 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 source. The internal circuit is initialized by the input of “L”. 20 to 27 22 to 29 P00/INT20 to P07/INT27 E General-purpose I/O ports Also serve as an external interrupt 2 input (wake-up function). External interrupt 2 input is hysteresis input. 28 to 31 30 to 33 P10/INT10 to P13/INT13 E General-purpose I/O ports Also serve as external interrupt 1 input. External interrupt 1 input is hysteresis input. 32 to 35 34 to 37 P14 to P17 F General-purpose I/O ports 36 38 P20/EC H N-ch open-drain general-purpose I/O port Also serves as the external clock input for the timer. The peripheral is a hysteresis input type. 37 39 P21 I N-ch open-drain general-purpose I/O port 38 40 P22/TO I N-ch open-drain general-purpose I/O port Also serves as a timer output. 39 41 P23/SI H N-ch open-drain general-purpose I/O port Also serves as the data input for the 8-bit serial I/O. The peripheral is a hysteresis input type. 40 42 P24/SO I N-ch open-drain general-purpose I/O port Also serves as the data output for the 8-bit serial I/O. 41 43 P25/SCK H N-ch open-drain general-purpose I/O port Also serves as the clock I/O for the 8-bit serial I/O. The peripheral is a hysteresis input type. 42 44 P26 I N-ch open-drain general-purpose I/O port 43 45 P27/BUZ I N-ch open-drain general-purpose I/O port Also serves as a buzzer output. |
