Can I access using a size that hasn't been enabled?

Latest Updated:06/20/2013

Question:

There are access sizes specified in the I/O registers. Can I access using a size that hasn't been enabled?

Answer:

Using Access sizes that are not specified in the I/O registers will not read/write correctly. Please use access sizes that are specified.
The "I/O Registers" chapter of the hardware manual contains information on internal register addresses and bit configuration. Please refer to the section on your peripheral module for details.
