PERIPHERAL RESOURCES
The I/O ports are used as general-purpose input/output ports (parallel I/O ports). The MB60385 series model
is provided with 5 ports (34 inputs). The ports function as input/output pins for peripheral functions also.
An I/O port, using port data resister (PDR), outputs the output data to I/O pin and input a signal input to I/O port.
The port direction register (DDR) specifies direction of input/output of I/O pins on a bit-by-bit basis.
The following summarizes functions of the ports and sharing peripheral functions :
• Port 1 : General-purpose input/output port, used also for PPG timer output and input capture inputs.
• Port 2 : General-purpose input/output port, used also for reload timer input/output and external interrupt input.
• Port 3 : General-purpose input/output port, used also for A/D converter activation trigger pin.
• Port 4 : General-purpose input/output port, used also for UART input/output and CAN controller send/receive
• Port 5 : General-purpose input/output port, used also analog input pin.
• Port 1 registers include port 1 data register (PDR1) and port 1 direction register (DDR1).
• The bits configuring the register correspond to port 1 pins on a one-to-one basis.
