7 / 40 page  MB89950 Series 7 s PIN DESCRIPTION (Continued) *1: FPT-64P-M09 *2: MQP-64C-P01 Pin no. Pin name Circuit type Function QFP*1 MQFP*2 22 23 X0 A Clock oscillator pins 23 24 X1 21 22 MODA B Operation-mode select pin This pin is connected directly to VSS with pull down resistor. 19 20 RST C Reset I/O pin This pin consists of an N-ch open-drain output with a pull-up resistor and hysteresis input. A Low level is put out from this pin. A “LOW” voltage on this port generates a RESET condition 48 to 41 49 to 42 P00/SEG20 to P07/SEG27 D N-channel open-drain type general-purpose I/O ports Also serve as LCDC controller segment outputs. Switching between port output and segment output is performed by the mask option every 8 bits. 40 to 33 41 to 34 P10/SEG28 to P17/SEG35 D N-channel open-drain type general-purpose I/O ports Also serve as LCDC controller segment outputs. Switching between port output and segment output is performed by the mask option. 32 to 27 33 to 28 P20/SEG36 to P25/SEG41 D N-channel open-drain type general-purpose I/O ports Also serve as LCDC controller segment outputs. Switching between port output and segment output is performed by the mask option. 14 to 11 15 to 12 P30 to P31 F N-channel open-drain type general-purpose I/O ports 12 to 11 13 to 12 P32/V1 to P33/V2 D N-channel open-drain type general-purpose I/O ports Also serve as LCDC controller power supply. 15 16 P40 E General-purpose I/O port A pull-up resistor option is provided. 16 17 P41/PWM E General-purpose I/O port Serves as PWM timer toggle output (PWM). A pull-up resistor option is provided. 17 18 P42/PWC/INT1 E General-purpose I/O port Also serves as pulse-width count timer input (PWC) and external interrupt input (INT1) The PWC and INT1 inputs are of a hysteresis type. A pull-up resistor option is provided. 18 19 P43/SI E General-purpose I/O port Also serves as serial I/O and UART data input (SI) The SI input is of a hysteresis type. A pull-up resistor option is provided. 20 21 P44/SO E General-purpose I/O port Also serves as serial I/O and UART data output (SO). A pull-up resistor option is provided. |
