Instruction Set
75
use a combination of direct addressing and relative addressing. The
direct address of the byte to be tested is in the byte following the opcode.
The third byte is the signed offset byte. The CPU finds the conditional
branch destination by adding the 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.
