INSTRUCTION SET
MC68HC05PL4
REV 2.0
third byte to the program counter if the specified bit tests true. The bit to be tested
and its condition (set or clear) is part of the opcode. The span of branching is from
–128 to +127 from the address of the next location after the branch instruction.
The CPU also transfers the tested bit to the carry/borrow bit of the condition code
register.
Table 12-3
lists the jump and branch instructions.
