Notes on Register Bits:
1. Writing values into unused register bits has no effect. However, to ensure
software compatibility with future, feature-enhanced versions of the product,
unused register bits must be written with logic zero. Reading back unused
bits can produce either a logic one or a logic zero; hence unused register bits
should be masked off by software when read.
2. All configuration bits that can be written into can also be read back. This
allows the processor controlling the STXC to determine the programming
state of the device.
3. Writable normal mode register bits are cleared to logic zero upon reset unless
otherwise noted.
4. Writing into read-only normal mode register bit locations does not affect
STXC operation unless otherwise noted.
5. Certain register bits are reserved. These bits are associated with megacell
functions that are unused in this application. To ensure that the STXC
operates as intended, reserved register bits must only be written with logic
zero. Similarly, writing to reserved registers should be avoided.
