11 / 61 page MB90440G Series 11 (Continued) s INPUT LEVELS The input level of ports P00 to P37 can be selected to be either TTL- or CMOS - level. The initial setting is TTL - level. These settings are global for all P00 to P37, it is not possible to set different levels to each port. The input level of ports P40 to PA0 can be selected to be either CMOS- or AUTOMOTIVE - level. The initial setting is CMOS - level. This settings can be done for each port individually. Pin No. Pin name Circuit type Function 75 P96 D General I/O port. This function is enabled when CAN1 disables out- put. TX1 TX output pin for CAN1. This function is enabled when CAN1 en- ables output. 76 P97 D General I/O port. This function is always enabled. RX1 RX input pin for CAN1 interface. When the CAN function is used, output from the other functions must be stopped. 78 PA0 D General I/O port. This function is always enabled. INT3 External interrupt request input pin for INT2. Set the corresponding DDR register to input if this function is used. 34 AVCC Power supply Power supply pin for the A/D Converter. This power supply must be turned on or off while a voltage higher than or equal to AVCC is ap- plied to VCC. 37 AVSS Power supply Dedicated ground pin for the A/D Converter 35 AVRH Power supply External reference voltage pin for the A/D Converter. This power supply must be turned on or off while a voltage higher than or equal to AVRH is applied to AVCC. 36 AVRL Power supply External reference voltage pin for the A/D Converter 49 to 50 MD0 to MD1 C Input pins for specifying the operating mode. The pins must be di- rectly connected to VCC or Vss. 51 MD2 F Input pin for specifying the operating mode. The pin must be directly connected to VCC or Vss. 27 C This is the power supply stabilization capacitor pin. It should be con- nected externally to an 0.1 µF ceramic capacitor. 23, 84 VCC Power supply Voltage (5.0 V) input pin 11, 42 81 VSS Power supply Voltage (0.0 V) input pin |
