1. Reset value of PIO_PSR depends on the product implementation.
2. PIO_ODSR is Read-only or Read/Write depending on PIO_OWSR I/O lines.
3. Reset value of PIO_PDSR depends on the level of the I/O lines. Reading the I/O line levels requires the clock of the PIO
4. PIO_ISR is reset at 0x0. However, the first read of the register may read a different value as input changes may have
if an offset is not listed in the table it must be considered as reserved.
