In the tables that follow, the column “Reset State” indicates the reset state of the line with mnemonics.
Indicates whether the PIO Line resets in I/O mode or in peripheral mode. If “PIO” is mentioned, the PIO line is maintained in a static state as soon as the reset is released. As a result, the bit corresponding to the PIO line in the register PIO_PSR (Peripheral Status Register) resets low.
If a signal name is mentioned in the “Reset State” column, the PIO line is assigned to this function and the corresponding bit in PIO_PSR resets high. This is the case of pins controlling memories, in particular the address lines, which require the pin to be driven as soon as the reset is released.
Indicates whether the signal is input or output state.
Indicates whether pullup, pulldown, or nothing is enabled.
Indicates if Schmitt Trigger is enabled.
