22.3.2.24 Port S Input Register (PTIS)
1
Read: Anytime.
Write: Never, writes to this register have no effect.
This register always reads back the buffered state of the associated pins. This also can be used to detect
overload or short circuit conditions on output pins.

These registers are reset to zero. Two bus clock cycles after reset release the register values are updated with the associated
pin values.
