This page describes the following instruction:
- Group: PAIR
- Mnemonic: if
- Opcode: 222d, DEh
- Encoding: 1_101_1110b (PAIR_SRC_DST)
- Pseudo-code: if r==0 then pc=i else pc++
- I:INNER F:FALSE
- Source is the I register.
- If R IS zero, set the Program Counter to source.
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.
