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.
Control
Instructions
These instructions act on CPU registers and control CPU operation
during program execution.
