In the above table, an entry such as E8-EF indicates a continuous block of hex opcodes used for 8 different
registers, the register numbers of which are defined by the lowest three bits of the corresponding code. Non-
continuous blocks of codes, shown as 11→F1 (for example), are used for absolute jumps and calls, with the top 3
bits of the code being used to store the top three bits of the destination address.
The CJNE instructions use the abbreviation #d for immediate data; other instructions use #data.
