10.2.4 Bit Manipulation Instructions
10.2.5 Control Instructions
Rev. 2
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.
These register reference instructions control CPU operation during program
execution. Control instructions, listed in
