This page describes the following instruction:
- Group: PAIR
- Mnemonic: lf
- Opcode: 174d, AEh
- Encoding: 1_010_1110b (PAIR_SRC_DST)
- Pseudo-code: if r==0 then pc=ram[l][o] else pc++
- L:LOCAL F:FALSE
- Source is the memory cell at page L offset O.
- If R IS zero, set the Program Counter to source.
The 'L' source is the value of a memory cell in the L-page. See Page Registers for more information on the three page register (D, L, C). 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.
