9 / 57 page  MB89490 Series 9 s PIN DESCRIPTION (Continued) Pin number Pin name I/O circuit type Function MQFP*1/ QFP*2 LQFP*3 99 96 X0 A Connection pins for a crystal or other oscillator circuit. An external clock can be connected to X0. In this case, leave X1 open. 98 95 X1 49 46 X0A A Connection pins for a crystal or other oscillator circuit. An external clock can be connected to X0A. In this case, leave X1A open. 48 45 X1A 97 94 MOD0 B Input pin for setting the memory access mode. Connect directly to VSS. 95, 94 92, 91 P84, P83 J General-purpose CMOS input port. 96 93 RST C Reset I/O pin. The pin is an N-ch open-drain type with pull-up resistor and hysteresis input. The pin outputs an “L” level when an internal reset request is present. Inputting an “L” level initial- izes internal circuits. 2 to 9 99 to 6 P00 to P07 D General-purpose CMOS I/O port. 10 to 17 7 to 14 P10/INT00 to P17/INT07 E General-purpose CMOS I/O port. The pin is shared with external interrupt 0 input. 18 15 P20/TO0 F General-purpose CMOS I/O port. The pin is shared with 8/16-bit timer/counter 00 and 01 output. 19 16 P21/RMC E General-purpose CMOS I/O port. The pin is shared with remote receiver input. 20 17 P22/EC0 E General-purpose CMOS I/O port. The pin is shared with 8/16-bit timer/counter 00 and 01 input. 21 18 P23 F General-purpose CMOS I/O port. 22 19 P24/TO1 F General-purpose CMOS I/O port. The pin is shared with 8/16-bit timer/counter 10 and 11 output. 23 20 P25/EC1 E General-purpose CMOS I/O port. The pin is shared with 8/16-bit timer/counter 10 and 11 input. 24 21 P26/PWM0 F General-purpose CMOS I/O port. The pin is shared with PWM0 output. 25 22 P27/PWM1 F General-purpose CMOS I/O port. The pin is shared with PWM1 output. 32 to 39 29 to 36 P30/AN0/INT10 to P37/AN7/INT17 G General-purpose CMOS I/O port. The pin is shared with external interrupt 1 input and A/D converter input. 40 to 45 37 to 42 P40 to P45 H General-purpose N-ch open-drain I/O port. 46 43 P46/SCL H General-purpose N-ch open-drain I/O port. The pin is shared with I2C clock I/O. |
