Register I/O Address Offset
The base address of the Registers is defined in the CSIOP equation that occupies
256 bytes of address space and is defined by the user in PSDsoft. The lower address byte
A[7:0], or address offset, selects the register. Table 28 shows the address offset for all
MCUs except those Motorola microcontrollers with a 16-bit data bus. Table 28A shows the
address offset for Motorola MCUs in 16-bit mode.
For example, when the CSIOP is defined to occupy the address range of 1000h to 10FFh in
PSDabel, the address of the Port A Control Register is then 1002h.
