2.2 I/O SPACE
In the V40HL and V50HL, I/Os up to 64K bytes (32K words) can be accessed in an area independent of the memory.
The various on-chip peripheral LSIs are set by accessing the system I/O area.
Extended functions added to those of the V40 and V50 are mapped onto unused V40 and V50 registers and the reserved
area.
The I/O map is shown in Figure 2-3.
