*
Refer to the I/O Port Section on how to enable the Latched Address Output function.
Tables 5 and 5A show the offset address to the PSD7XX registers relative to the CSIOP
base address. The CSIOP space is the 256 bytes of address that is allocated by the user to
the internal PSD7XX registers. Some Motorola 16-bit microcontrollers, including the
M68HC16, M68302 and M683XX, have a different data byte orientation requiring separate
address offset maps.
Table 5 shows the CSIOP address offsets for all MCUs except those from Motorola in 16-bit
mode. Table 5A shows the address offsets for Motorola MCUs in 16-bit mode.
