8.4 Port 1

Operation of Port 1

This section describes the operation of port 1.

s Operation of Port 1

r Setting Port 1 as an output port in the Port 1 direction register (DDR1)

Setting Port 1 as an output port in the Port 1 direction register (DDR1)

The value stored in the Port 1 data register (PDR1) is output to the Port 1 pin. If the PDR1

r Setting Port 1 as an input port in the Port 1 direction register (DDR1)

The Port 1 pin has high impedance. However, the Port 1 pin retains the "H" level if the bit in

the Port 1 pull-up resistor register (RDR1) is set to "1" and thus the pull-up resistor is

If the Port 1 data register (PDR1) is set to a value, the value stored in the PDR1 register is

retained but not output to the pin.

If the PDR1 register is read, the pin input level ("0" for "L" or "1" for "H") is output.

If a read-modify-write instruction (such as the bit set instruction) is used to access the PDR1

input in the DDR1 register, however, the pin input level is written to the PDR1 register.

Therefore, to change a bit specified for input to output, first write an output value to the

PDR1 register and then specify the DDR1 register as an output port.

r Port operation after a reset

When the CPU is reset, the DDR1 and RDR1 registers are initialized to "00H" and the Port 1

pin has high impedance.

The PDR1 register is not initialized when the CPU is reset. To use the port in output mode,

therefore, output mode must be specified in the DDR1 register after the output data is set in

the PDR1 register.

r Port operation in stop or time-base timer mode

If the port switches to stop mode or timebase timer mode while the pin status setting bit (SPL) of

the low power consumption mode control register (LPMCR) is set to "1", the pins come to have

high impedance regardless of the value in the Port 1 direction register (DDR1). Note that the

input buffer is forcibly shut off to prevent leakage due to an open circuit.

If a pull-up resistor is connected, setting the pin status setting bit (SPL) of the low power

consumption mode control register (LPMCR) to "1" does not disconnect the pull-up resistor

but holds the pin level at "H".
