Pin Functions
Port group overview
Note
Table 2-1
Pin configuration
Table 2-1 gives an overview of the port groups. For each port group it shows
the supported functions in port mode and in alternative mode. Any port group
can operate in 8-bit or 1-bit units. Port groups 3, 6, 9 and DL can additionally
operate in 16-bit units.
Not all port groups and functions in Table 2-1 are available for all products of
the V850ES/Fx3-L product line. For detailed information which port groups and
functions are available for a dedicated product, refer to "2.4 Port Type
Diagrams" .

To define the function and the electrical characteristics of a pin, several control
registers are provided.
• For a general description of the registers, see "Port Group Configuration
Registers" on page 36.
• For every port, detailed information on the configuration registers is given in
