Note 1
: For details of the functions of ports P0 to P3 in modes other than single-chip mode, and how to use double-function ports as func-
tion I/O ports, refer to the applicable sections.
2
: Make sure that the input level at each pin is either 0 V or V
CC
during execution of the STP instruction.
When an input level is at an intermediate potential, a current will flow from V
CC
to V
SS
through the input-stage gate.
I/O Ports
Direction registers
The 3802 group has 56 programmable I/O pins arranged in seven
I/O ports (ports P0 to P6). The I/O ports have direction registers
which determine the input/output direction of each individual pin.
Each bit in a direction register corresponds to one pin, each pin
can be set to be input port or output port.
When “0” is written to the bit corresponding to a pin, that pin be-
comes an input pin. When “1” is written to that bit, that pin be-
comes an output pin.
If data is read from a pin which is set to output, the value of the
port output latch is read, not the value of the pin itself. Pins set to
input are floating. If a pin set to input is written to, only the port
output latch is written to and the pin remains floating.
