11 / 118 page MB90470 Series 11 (Continued) LQFP : FPT-100P-M05 package QFP : FPT-100P-M06 package Pin no. Pin name Circuit type Description LQFP QFP 72 74 P54 D (CMOS) General purpose input/output port. In external bus mode, this pin functions as the HRQ pin when the HDE bit in the EPCR register is set to “1”. HRQ In external bus mode, this pin functions as the hold request input (HRQ) pin. When the HDE bit in the EPCR register is set to “0”,this pin functions as a general purpose input/output port. 73 75 P55 D (CMOS) General purpose input/output port. In external bus mode, this pin functions as the HAK pin when the HDE bit in the EPCR register is set to “1”. HAK In external bus mode, this pin functions as the hold acknowl- edge output (HAK) pin. When the HDE bit in the EPCR register is set to “0”,this pin functions as a general purpose input/output port. 74 76 P56 D (CMOS) General purpose input/output port. In external bus mode, this pin functions as the DRY pin when the RYE bit in the EPCR register is set to “1”. RDY In external bus mode, this pin functions as the external ready input (RDY) pin. When the RYE bit in the EPCR register is set to “0”,this pin functions as a general purpose input/output port. 76 78 P57 D (CMOS) General purpose input/output port. In external bus mode, this pin functions as the CLK pin when the CKE bit in the EPCR register is set to “1”. CLK In external bus mode, this pin functions as the machine cycle clock output (CLK) pin. When the CKE bit in the EPCR register is set to “0”,this pin functions as a general purpose input/output port. 36 to 39 38 to 41 P60 to P63 H (CMOS) General purpose input/output ports.
