8 / 64 page MB90550A/550B Series 8 DS07-13706-6E (Continued) Pin no. Pin name Circuit type Function QFP LQFP 14 12 P34 E (CMOS) General-purpose I/O port. This function is enabled in single-chip mode HRQ Hold request input pin. This function is enabled in an external-bus enabled mode. 15 13 P35 E (CMOS) General-purpose I/O port. This function is enabled in single-chip mode. HAK Hold acknowledge output pin. This function is enabled in an external-bus enabled mode. 16 14 P36 E (CMOS) General-purpose I/O port. This function is enabled in single-chip mode. RDY Ready signal input pin. This function is enabled in an external-bus enabled mode. 17 15 P37 E (CMOS) General-purpose I/O port. This function is enabled in single-chip mode. CLK CLK output pin. This function is enabled in an external-bus enabled mode. 18 16 P40 F (CMOS/H) General-purpose I/O port. Serves as an open-drain output port (OD40 = 1) depending on the setting of the open-drain control setting register (ODR4). (D40 = 0: Disabled when the port is set for input.) SCK UART serial clock I/O pin. This function is enabled with the UART clock output enabled. 19 17 P41 F (CMOS/H) General-purpose I/O port. Serves as an open-drain output port (OD41 = 1) depending on the setting of the open-drain control setting register (ODR4). (D41 = 0: Disabled when the port is set for input.) SOT UART serial data output pin. This function is enabled with the UART serial data output enabled. 20 18 P42 F (CMOS/H) General-purpose I/O port. Serves as an open-drain output port (OD42 = 1) depending on the setting of the open-drain control setting register (ODR4). (D42 = 0: Disabled when the port is set for input.) SIN UART serial data input pin. Since this input is used as required while the UART is operating for input, the output by any other function must be off unless used intentionally. 21 19 P43 F (CMOS/H) General-purpose I/O port. Serves as an open-drain output port (OD43 = 1) depending on the setting of the open-drain control setting register (ODR4). (D43 = 0: Disabled when the port is set for input.) SCK1 Extended I/O serial clock I/O pin. This function is enabled with the extended I/O serial clock output enabled. |
