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
5. Only this set of registers clears the status by writing 1 in the first register and sets the status by writing 1 in the second
Controller to be enabled, otherwise PIO_PDSR reads the levels present on the I/O line at the time the clock was disabled.
