8 / 113 page MB90480/485 Series 8 s s s s PIN DESCRIPTIONS (Continued) Pin No. Pin name Circuit type Function LQFP*1 QFP*2 80 82 X0 A Oscillator pin 81 83 X1 A Oscillator pin 78 80 X0A A 32 kHz oscillator pin 77 79 X1A A 32 kHz oscillator pin 75 77 RST B Reset input pin 83 to 90 85 to 92 P00 to P07 C (CMOS) This is a general purpose I/O port. A setting in the pull-up resistance setting register (RDR0) can be used to apply pull-up resistance (RD00- RD07 = “1”) . (Disabled when pin is set for output.) AD00 to AD07 In multiplex mode, these pins function as the external address/data bus low I/O pins. D00 to D07 In non-multiplex mode, these pins function as the external data bus low output pins. 91 to 98 93 to 100 P10 to P17 C (CMOS) This is a general purpose I/O port. A setting in the pull-up resistance setting resister (RDR1) can be used to apply pull-up resistance (RD10- RD17 = “1”) . (Disabled when pin is set for output.) AD08 to AD15 In multiplex mode, these pins function as the external address/data bus high I/O pins. D08 to D15 In non-multiplex mode, these pins function as the external data bus high output pins. 99, 100, 1,2 1 to 4 P20 to P23 E (CMOS/H) This is a general purpose I/O port. When the bits of external address output control register (HACR) are set to "1" in external bus mode, these pins function as general purpose I/O ports. A16 to A19 When the bits of external address output control register (HACR) are set to "0" in multiplex mode, these pins function as address high output pins (A16-A19). A16 to A19 When the bits of external address output control register (HACR) are set to "0" in non-multiplex mode, these pins function as address high output pins (A16-A19). 3 to 6 5 to 8 P24 to P27 E (CMOS/H) This is a general purpose I/O port. When the bits of external address output control register (HACR) are set to "1" in external bus mode, these pins function as general purpose I/O ports. A20 to A23 When the bits of external address output control register (HACR) are set to "0" in multiplex mode, these pins function as address high output pins (A20-A23). A20 to A23 When the bits of external address output control register (HACR) are set to "0" in non-multiplex mode, these pins function as address high output pins (A20-A23). PPG0 to PPG3 PPG timer output pins. 79 P30 E (CMOS/H) This is a general purpose I/O port. A00 In non-multiplex mode, this pin functions as an external address pin. AIN0 8/16-bit up/down timer input pin (channel 0) . |
