8 / 48 page  MB89470 Series 8 s PIN DESCRIPTION (Continued) Pin no. Pin name I/O circuit Function LQFP/QFP/ MQFP*2 SDIP*1 17 47 X0 A Connection pins for a crystal or other oscillator. An external clock can be connected to X0. In this case, leave X1 open. 18 48 X1 16 46 MODE B Input pins for setting the memory access mode. Connect directly to VSS. 14 44 RST C Reset I/O pin. The pin is a N-ch open-drain type with pull-up resistor and a hysteresis input. The pin outputs an “L” level when an internal reset request is present. Inputting an “L” level initializes internal cir- cuits. 38 to 31 20 to 13 P00/AN0 to P07/AN7 D General-purpose I/O port. The pins are shared with the analog inputs for the A/D converter. 30 to 27 12 to 9 P10/INT10 to P13/INT13 E General-purpose I/O port. A hysteresis input for INT10 to INT13. The pin is shared with an external interrupt 1 input. 26 8 P14/EC1 E General-purpose I/O port. A hysteresis input for EC1. The pin is shared with the 8/16 bit timer 1 input. 25 7 P15/TO1 F General-purpose I/O port. The pin is shared with the output of 8/16-bit timer 1. 24 6 P16/EC2 E General-purpose I/O port. A hysteresis input for EC2. The pin is shared with the 8/16 bit timer 2 input. 23 5 P17/TO2 F General-purpose I/O port. The pin is shared with the output of 8/16-bit timer 2. 13 43 P20/SCK1 E General-purpose I/O port. A hysteresis input for SCK1. The pin is shared with the clock I/O of UART/SIO 1. 12 42 P21/SO1 F General-purpose I/O port. The pin is shared with the serial data output of UART/SIO 1. 11 41 P22/SI1 E General-purpose I/O port. A hysteresis input for SI1. The pin is shared with the serial data input of UART/SIO 1. 10 40 P23/PWC E General-purpose I/O port. A hysteresis input for PWC. This pin is shared with PWC input. 939 P24/PWM F General-purpose input port. This pin is shared with PWM output. 8 38 P25/SI2 E General-purpose I/O port. A hysteresis input for SI2. The pin is shared with the serial data input of UART/SIO 2. |
