The Branch on Equal Sign and Carry opcode (BESC) is a two-decle opcode that is a part of the [[Branch]] family of opcodes. This instruction causes the [[CP1610]] to branch if the [[Carry Flag]] is equal to the [[Sign Flag]] to the address specified by the following parameters.<br/><br />
<br />
Format - Decle #1 Format - Word #2 (Unknown if all 16 bits are significant)<br />
0000:0010:00d0:1111 aaaa:aaaa:aaaa:aaaa<br/><br />
where:<br/><br />
d indicates the direction of the branch<br />
such that:<br />
d == 0 indicates to branch in the forward direction<br />
d == 1 indicates to branch in the reverse direction<br/><br />
aaaaaaaaaaaaaaaa indicates the amount of offset<br />
<br />
See the [[Branch]] opcode family documentation for more information.</div>Pingaso
