A11, A12 In non-multiplex mode, these pins function as external address pins. P43, P44 F (CMOS) MB90485B series This is a general purpose I/O port. A11, A12 In non-multiplex mode, these pins function as external address pins. MT00, MT01 μPG output pins 24 22 P45 F (CMOS) MB90480B series This is a general purpose I/O port. A13 In non-multiplex mode, this pin functions as an external address pin. P45 G (CMOS/H) MB90485B series This is a general purpose I/O port. A13 In non-multiplex mode, this pin functions as an external address pin. EXTC*4 μPG input pin. 25, 26 23, 24 P46, P47 F (CMOS) This is a general purpose I/O port. A14, A15 In non-multiplex mode, these pins function as external address pins. OUT4, OUT5 Output compare event output pins. 70 68 P50 D (CMOS) This is a general purpose I/O 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 (ALE) signal pin. 71 69 P51 D (CMOS) This is a general purpose I/O 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) signal pin. 72 70 P52 D (CMOS) This is a general purpose I/O port. In external bus mode, when the WRE bit in the EPCR register is set to “1”, this pin functions as the WRL pin. 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 I/O port. 73 71 P53 D (CMOS) This is a general purpose I/O port. In external bus mode with 16-bit bus width, when the WRE bit in the EPCR register is set to “1”, this pin functions as the WRH pin. WRH In external bus mode with 16-bit bus width, this pin functions as the upper 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 I/O port. |
