10 / 48 page MB89180L Series 10 s PIN DESCRIPTION (Continued) Pin no. Pin name I/O circuit type Function SQFP*1 QFP*2 MQFP*3 QFP*4 39 40 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. 38 39 X1 40 41 MODA C Memory access mode setting pin. Connect directly to VSS. 43 44 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”. 44 to 51 45 to 52 P07/INT27 to P00/INT20 E General-purpose I/O ports. Also serve as an external interrupt 2 input (wake-up function). External interrupt 2 input is hysteresis input. 21 to 23 22 to 24 P10/SEG24/ INT10 to P12/SEG26/ INT12 E/K General-purpose I/O ports. Also serve as input for external interrupt 1 input. The interrupt 1 input is a hysteresis type. Also serve as LCD controller/driver segment output. Switching is done by the mask option. 25 26 P13/SEG27/ INT13 26 to 29 27 to 30 P14/SEG28 to P17/SEG31 F/K General-purpose I/O ports. Also serve as LCD controller/driver segment output. Switching is done by the mask option. 37 38 P20/EC H General-purpose N-ch open-drain I/O port. Also serves as the external clock input for the 8-bit timer counter. The resource is a hysteresis input type. 36 37 P21 I General-purpose N-ch open-drain I/O port. 35 36 P22/TO I General-purpose N-ch open-drain I/O port. Also servers as the 8-bit timer/counter output. 34 35 P23/SI H N-ch open-drain general-purpose I/O port. Also serves as the data input for the serial I/O. The peripheral is a hysteresis input type. 33 34 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. 32 33 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. 31 32 P26 I N-ch open-drain general-purpose I/O port. |
