Notes:

1. Refer to peripheral multiplexing tables in Section 7.4 “Peripheral Signals Multiplexing on I/O Lines” for these signals.

2. When configured as an input, the NRST pin enables asynchronous reset of the device when asserted low. This allows

connection of a simple push button on the NRST pin as a system-user reset.

3. Programming of this pull-up resistor is performed independently for each I/O line through the PIO Controllers. After reset, all

the I/O lines default as inputs with pull-up resistors enabled, except those which are multiplexed with the External Bus

Interface signals that require to be enabled as Peripheral at reset. This is explicitly indicated in the column “Reset State” of

the peripheral multiplexing tables.
