This page describes the following instruction:
- Group: PAIR
- Mnemonic: nf
- Opcode: 142d, 8Eh
- Encoding: 1_000_1110b (PAIR_SRC_DST)
- Pseudo-code: if r==0 then pc=ram[c][pc] else pc++
- N:NUMBER F:FALSE
- Source is the literal following the current opcode.
- If R IS zero, set the Program Counter to source.
The 'N' source is a literal byte embedded in the instruction stream. Reading 'N' acts in the same way as an instruction fetch, only it fetches a literal. The 'F' destination takes the source value as the target offset of a conditional jump (R==0) to within the current code page. See In-Page Branching for more on this.
