4.2 Control Parameters (Latches/Registers)
These cells can be either read-only or write-only. In the Motorola Mode the
VPC3+S carries out ‘address swapping’ for an access to the address
locations 00H - 07H (word registers). That is, the VPC3+S internally
generates an even address from an odd address and vice-versa.
