write only; the read function is unimplemented. Reading of write-only I/O
bits has no effect on MCU operation. In register figures, the read function
of write-only bits is shaded.
Some addresses are reserved. Writing to a reserved address can
have unpredictable effects on MCU operation. In the memory map,

addresses are marked with the word reserved.
Some I/O bits are reserved. Writing to a reserved bit can have
unpredictable effects on MCU operation. In register figures, reserved
bits are marked with the letter R.
