I/O
General-purpose I/O ports with shared functions as serial I/O ports.
The input formats are Schmitt inputs. The PE1/SCK2 and PE2/SO2
pins can be switched to function as open drain outputs.
The IOS1 instruction is used to switch between the general-purpose
I/O port and serial I/O port functions.
When used as general-purpose I/O ports :
The pins are set to the general-purpose I/O port function using the
IOS1 instruction.
The mode (input or output) is set in 1-bit units using the IOS1
instruction
When used serial I/O ports :
The pins are set to the serial I/O port function using the IOS1
instruction.
[Pin states when set to the serial I/O port function]
PE0, PF0, PG0 … General-purpose I/O
PE1, PF1, PG1 … SCK input or output
PE2, PF2, PG2 … SO output
PE3, PF3, PG3 … SI input
The PE1/SCK2 and PE2/SO2 pins can be switched to function as
open drain outputs with the IOS2 instruction. When using this circuit
type, the external pull-up resistors must be connected to the same
power supply as that used by the IC.
Input is disabled and the pins go to the high-impedance state in
Backup mode.
These ports are set up as general-purpose input ports after a power
on reset.

Main charge pump outputs.
These pins output a high level when the frequency of the local
oscillator divided by n is higher than that of the reference frequency,
and they output a low level when that frequency is lower.
They go to the high-impedance state when the frequencies match.
These pins go to the high-impedance state in Backup mode, after a
power on reset, and in the PLL stopped state.

Power supply connections.
The VDDPORT and VSSPORT pins are mainly supply power for the
peripheral I/O blocks.
The VDDPLL and VSSPLL pins are mainly for the PLL circuits and
the regulator.
The VSSCPU pin is mainly used by the CPU block.
The VSSADC pin is mainly used by the ADC block.
Since all the VDD and VSS pins are independent, all must be
connected to the same power supply.
