2.2.4 Configuration of electrical characteristics
(1)
(2)
The registers for the configuration of electrical characteristics are briefly
described in the following. For details refer to the Electrical Target
Specification.
PDSCn - Port drive strength control register
The 8-bit PDSCn register selects the output current limiting function for high- or
low-drive strength.
This register can be read/written, in 8-bit and 1-bit units.
see “Port Group Configuration“ on page 56

PDSCn register contents
For the detailed specification of "Limit 1" and "Limit 2" refer to the Electrical
Target Specification.
PICCn - Port input characteristic control register
The 8-bit PICCn register selects between Schmitt Trigger or non-Schmitt
Trigger input characteristics.
This register can be read/written in 8-bit and 1-bit units.
