11 / 113 page MB90480/485 Series 11 (Continued) Pin No. Pin name Circuit type Function LQFP*1 QFP*2 74 76 P56 D (CMOS) This is a general purpose I/O port. In external bus mode, when the RYE bit in the EPCR register is set to “1”, this pin functions as the RDY pin. RDY In external bus mode, this pin functions as the external ready (RDY) input pin. When the RYE bit in the EPCR register is set to “0”, this pin functions as a general purpose I/O port. 76 78 P57 D (CMOS) This is a general purpose I/O port. In external bus mode, when the CKE bit in the EPCR register is set to “1”, this pin functions as the CLK pin. CLK In external bus mode, this pin functions as the machine cycle clock (CLK) output pin. When the CKE bit in the EPCR register is set to “0”, this pin functions as a general purpose I/O port. 36 to 39 38 to 41 P60 to P63 H (CMOS) These are general purpose I/O ports. AN0 to AN3 These are the analog input pins. 41 to 44 43 to 46 P64 to P67 H (CMOS) These are general purpose I/O ports. AN4 to AN7 These are the analog input pins. 25 27 P70 G (CMOS/ H) This is a general purpose I/O port. SIN0 This is the UART data input pin. 26 28 P71 F (CMOS) This is a general purpose I/O port. SOT0 This is the UART data output pin. 27 29 P72 G (CMOS/ H) This is a general purpose I/O port. SCK0 This is the UART clock I/O pin. 28 30 P73 G (CMOS/ H) This is a general purpose I/O port. TIN0 This is the 16-bit reload timer event input pin. 29 31 P74 F (CMOS) This is a general purpose I/O port. TOT0 This is the 16-bit reload timer output pin. 30 32 P75 F (CMOS) MB90480 series This is a general purpose I/O port. P75 G (CMOS/ H ) MB90485 series This is a general purpose I/O port. PWC2*3 This is a PWC input pin. 31 33 P76 F (CMOS) MB90480 series This is a general purpose I/O port. P76 I (NMOS/ H) MB90485 series This is a general purpose I/O port. SCL*3 Serves as the I2C interface data I/O pin. During operation of the I2C interface, leave the port output in a high impedance state. 32 34 P77 F (CMOS) MB90480 series This is a general purpose I/O port. P77 I (NMOS/ H) MB90485 series This is a general purpose I/O port. SDA*3 Serves as the I2C interface data I/O pin. During operation of the I2C interface, leave the port output in a high impedance state. 45, 46 47, 48 P80, P81 E (CMOS/ H ) These are general purpose I/O ports. IRQ0, IRQ1 External interrupt input pins. |
