4.6 Peripheral Memory Mapped Registers

On-chip peripheral registers are part of the data memory map on the 56800E series. These locations may

be accessed with the same addressing modes used for ordinary Data memory, except all peripheral

registers should be read/written using word accesses only.

Table 4-6 summarizes base addresses for the set of peripherals on the 56F8014 device. Peripherals are

listed in order of the base address.
