The pin descriptions for all external pins with the exception of the EEPROM VDDP and VSSP pins are
described in the preceding MCU section.
VDDP and VSSP should be externally connected to the MCU power supply named VDD and VSS respectively.
The SDA and SCL lines here are internal connected to the MCU I/O pins PC0 and PC1 respectively for these
devices.
