The MPU is capable of altering any bits residing in the first 256 bytes of memory. An
additional feature allows the software to test and branch on the state of any bit within these
locations. For test and branch instructions the value of the bit tested is placed in the carry bit
of the condition code register.
If a specific condition is met, the instruction branches. If not, no operation is performed.
