Pin name Circuit type Description LQFP QFP 18 20 P42 G (CMOS/H) General purpose input/output port. A10 In non-multibus bus mode, this pin functions as an external address pin. SCK2 Single serial I/O clock input/output pin 19 20 21 22 P43, P44 F (CMOS) General purpose input/output ports. A11, A12 In non-multibus bus mode, this pin functions as an external address pin. MT00, MT01 µPG input pins 22 24 P45 G (CMOS/H) General purpose input/output ports. A13 In non-multibus bus mode, this pin functions as an external address pin. EXTC µPG input pin 23 24 25 26 P46, P47 F (CMOS) General purpose input/output ports. A14, A15 In non-multibus bus mode, this pin functions as an external address pin. OUT4/OUT5 Output compare event output pins 68 70 P50 D (CMOS) General purpose input/output port. In external bus mode, this pin functions as the ALE pin ALE In external bus mode, this pin functions as the address load enable signal (ALE) pin 69 71 P51 D (CMOS) General purpose input/output port. In external bus mode, this pin functions as the RD pin. RD In external bus mode, this pin functions as the read strobe output (RD) pin. 70 72 P52 D (CMOS) General purpose input/output port. In external bus mode, this pin functions as the WRL pin when the WRE bit in the EPCR register is set to “1”. WRL In external bus mode, this pin functions as the lower data write strobe output (WRL) pin. When the WRE bit in the EPCR register is set to “0”,this pin functions as a general purpose input/output port. 71 73 P53 D (CMOS) General purpose input/output port. In external bus mode with 16-bit bus width, this pin functions as the WRH pin when the WRE bit in the EPCR register is set to “1”. WRH In external bus mode with 16-bit bus width, this pin functions as the higher data write strobe output (WRH) pin. When the WRE bit in the EPCR register is set to “0”,this pin functions as a general purpose input/output port. |
