Function faucon_asm::opcode::get_opcode_form

pub const fn get_opcode_form(opcode: u8) -> (u8, u8)

Extracts the instruction form from a given opcode.

The returned tuple (a, b) contains the two parts of the opcode that decide its form. If a is 0-2, then b decides on a form within the group denoted by a. If a is 3, then b ultimately decides on the form.
