The Branch on No Overflow opcode (BNOV) is a two-decle opcode that is a part of the Branch family of opcodes. This instruction causes the CP1610 to branch if the Overflow Flag is set to the address specified by the following parameters.
Format - Decle #1 Format - Word #2 (Unknown if all 16 bits are significant) 0000:0010:00d0:1010 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
