11.4.4 Bit Manipulation Instructions
The CPU can set or clear any writable bit in the first 256 bytes of
memory. Port registers, port data direction registers, timer registers, and
on-chip RAM locations are in the first 256 bytes of memory. The CPU
can also test and branch based on the state of any bit in any of the first
256 memory locations. Bit manipulation instructions use direct
addressing. Table 11-4 lists these instructions.
11.4.5 Control Instructions
These register reference instructions control CPU operation during
program execution. Control instructions, listed in Table 11-5, use
inherent addressing.
