Central Processor Unit (CPU)
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.
4.6.2.5 Control Instructions
These instructions act on CPU registers and control CPU operation during program execution.
