This page describes the following instruction:
- Group: PAIR
- Mnemonic: rw
- Opcode: 204d, CCh
- Encoding: 1_100_1100b (PAIR_SRC_DST)
- Pseudo-code: if i!=0 then pc=r else pc++; i--
- R:RESULT W:WHILE
- Source is the R register.
- If I is NOT zero, set the Program Counter to source. Then in either case decrement I.
The 'W' destination takes the source value as the target offset of a conditional jump (I != 0) to within the current code page. See In-Page Branching for more on this.
