* One-byte instruction only when [TDE], [WHL], [TDE+], [TDE-], [WHL+] or [WHL–] is written as mem in an MOV
For some instructions that include saddr, saddrp, r or rp in their operands, two “Bytes” entries are given, separated
by a slash (“/”). The entry that applies is shown in the table below.
Operands TDE, WHL, VVP and UUP (24-bit registers) can also be written as DE, HL, VP and UP respectively. However,
they are still treated as TDE, WHL, VVP and UUP (24-bit registers) when written as DE, HL, VP and UP.
