7 / 107 page  MB90630A Series 7 (Continued) STBC: Incorporates standby control *1: LQFP (FPT-100P-M05) *2: QFP (FPT-100P-M06) Pin no. Pin name Circuit type Function LQFP*1 QFP*2 12 14 P34 H (STBC) General-purpose I/O port Functions as the HRQ pin in external bus mode if the HDE bit in the EPCR register is “1”. HRQ Functions as the hold request input pin (HRQ). 13 15 P35 H (STBC) General-purpose I/O port Functions as the HAK pin in external bus mode if the HDE bit in the EPCR register is “1”. HAK Functions as the hold acknowledge output (HAK) pin. 14 16 P36 H (STBC) General-purpose I/O port Functions as the RDY pin in external bus mode if the RYE bit in the EPCR register is “1”. RDY Functions as the external ready input (RDY) pin. 15 17 P37 H (STBC) General-purpose I/O port Functions as the CLK pin in external bus mode if the CKE bit in the EPCR register is “1”. CLK Functions as the machine cycle clock output (CLK) pin. 16 18 P40 G (STBC) General-purpose I/O port When UART0 is operating, the data at the pin is used as the serial input (SIN0). Can be set as an open-drain output port (OD40 = “1”) by the open-drain control register (ODR4). The setting does not apply for ports set as inputs (D40 = “0”: invalid at the input setting). SIN0 Functions as the UART0 serial input (SIN0). 17 19 P41 F (STBC) General-purpose I/O port Functions as the SOT0 pin if the SOE bit in the UMC register is “1”. Can be set as an open-drain output port (OD41 = “1”) by the open-drain control register (ODR4). The setting does not apply for ports set as inputs (D41 = “0”: invalid at the input setting). SOT0 Functions as the UART0 serial data output pin (SOT0). 18 20 P42 G (STBC) General-purpose I/O port When UART0 is operating in external shift clock mode, the data at the pin is used as the clock input (SCK0). Also, functions as the SCK0 pin if the SOE bit in the UMC register is “1”. Can be set as an open-drain output port (OD42 = “1”) by the open-drain control register (ODR4). The setting does not apply for ports set as inputs (D42 = “0”: invalid at the input setting). SCK0 Functions as the UART0 serial clock I/O pin (SCK0). |
