8 / 118 page MB90470 Series 8 s PIN DESCRIPTION (Continued) LQFP : FPT-100P-M05 package QFP : FPT-100P-M06 package Pin no. Pin name Circuit type Description LQFP QFP 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) General purpose input/output ports. Set the pull-up resistance setting register (RDR0) to add pull-up resistance (RD00-RD07 = “1” ) . (Not valid when set for output) AD00 to AD07 In multiplex mode, these pins function as external address/ data bus lower input/output pins. D00 to D07 In non-multiplex mode, these pins function as external data bus lower output pins. 91 to 98 93 to 100 P10 to P17 C (CMOS) General purpose input/output ports. Set the pull-up resistance setting register (RDR1) to add pull-up resistance (RD10-RD17 = “1” ) . (Not valid when set for output) AD08 to AD15 In multiplex mode, these pins function as external address/ data bus higher input/output pins. D08 to D15 In non-multiplex mode, these pins function as external data bus higher output pins. 99 100 1 2 1 to 4 P20 to P23 E (CMOS/H) General purpose input/output ports. In external bus mode, pins for which the corresponding bit in the external address output control register (HACR) is “1” function as the general purpose input/output ports. A16 to A19 In multiplex mode, pins for which the corresponding bit in the external address output control register (HACR) is “0” function as the upper address output pins (A16 to A19) . A16 to A19 In non-multiplex mode, pins for which the corresponding bit in the external address output control register (HACR) is “0” function as the upper address output pins (A16 to A19) . 3 to 6 5 to 8 P24 to P27 E (CMOS/H) General purpose input/output ports. In external bus mode, pins for which the corresponding bit in the external address output control register (HACR) is “1” function as the general purpose input/output ports. A20 to A23 In multiplex mode, pins for which the corresponding bit in the external address output control register (HACR) is “0” function as the upper address output pins (A20 to A23) . A20 to A23 In non-multiplex mode, pins for which the corresponding bit in the external address output control register (HACR) is “0” function as the upper address output pins (A20 to A23) . PPG0 to PPG3 PPG timer output pins. |
