4.6.2.4 Bit Manipulation Instructions
The CPU can set or clear any writable bit in the first 256 bytes of memory, which
includes I/O registers and on-chip RAM locations. The CPU can also test and
branch based on the state of any bit in any of the first 256 memory locations.
NOTE:
Do not use bit manipulation instructions on registers with write-only bits.
4.6.2.5 Control Instructions
These instructions act on CPU registers and control CPU operation during program
execution.
