• Manufacturer Part Number: UPD70208HGF-12-3B9
• Description: V40HLTM, V50HLTM 16/8, 16-BIT MICROPROCESSOR
• Manufacturer: NEC [NEC]

following conditions.
(1) V40HL
The instruction set is shown in tabular form on the following pages.
Clock cycle shown in table is the time required for execution of instruction by the execution unit and is based on the
The number of clock cycle of instruction with byte processing and word processing (with W bit) is shown as the followings.
For the clock of block transfer related instruction of V40HL, see Table 15-8.
On the left of "/"
On the right of "/": The value corresponding to word processing (W =1) of odd address
• Prefetch time and wait time for using bus, etc. are not included.
• 0 wait is assumed for memory access. That is, the clock number of one bus cycle is four clock cycle.
• 0 wait is assumed for I/O access.
• Primitive block transfer instruction and primitive input/output instruction is included repeat prefixes.
