The Unconditional Branch opcode (B) is a two-decle opcode that is a part of the Branch family of opcodes. The Unconditional Branch causes the CP1610 to always branch to the address specified by the following parameters.

   Format - Decle #1    Format - Word #2 (All 16 bits are significant)
   0000:0010:00d0:0000  aaaa:aaaa:aaaa:aaaa
where:
d indicates the direction of the branch such that: d == 0 indicates to branch in the forward direction d == 1 indicates to branch in the reverse direction
aaaaaaaaaaaaaaaa indicates the amount of offset
