Port and control configuration:
●
●
The reset configuration of each pin is shown in bold. This configuration is valid as long as
the device is in reset state.
On the chip, each I/O port may have up to 8 pads. Pads that are not bonded to external pins
are set in input pull-up configuration after reset through the option byte Package selection.
The configuration of these pads must be kept at reset state to avoid added current
consumption.
