disabled, and the pin is capable of analog functions.
0 The analog function of the pin is disabled, the isolation is
enabled, and the pin is capable of digital functions as specified
by the other GPIO configuration registers.
Note: This register and bits are only valid for GPIO signals that
share analog function through a unified I/O pad.
The reset state of this register is 0 for all signals.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
