Register 70: General-Purpose Input/Output Software Reset (SRGPIO), offset
0x508
The SRGPIO register provides software the capability to reset the available GPIO modules.
A peripheral is reset by software using a simple two-step process:
1. Software sets a bit (or bits) in the SRGPIO register. While the SRGPIO bit is 1, the peripheral
is held in reset.
2. Software completes the reset process by clearing the SRGPIO bit.
There may be latency from the clearing of the SRGPIO bit to when the peripheral is ready for use.
Software should check the corresponding PRGPIO bit to verify that the GPIO Module registers are
ready to be accessed.
Important: This register should be used to reset the GPIO modules.

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.
