13.3.3 Jump/Branch Instructions
Jump instructions allow the CPU to interrupt the normal sequence of the program counter. The
unconditional jump instruction (JMP) and the jump-to-subroutine instruction (JSR) have no register
operand. Branch instructions allow the CPU to interrupt the normal sequence of the program counter
when a test condition is met. If the test condition is not met, the branch is not performed.
The BRCLR and BRSET instructions cause a branch based on the state of any readable bit in the first
256 memory locations. These 3-byte instructions 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 effective 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.
