4.6 EOnCE Memory Map
4.7 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 4-7 summarizes base addresses for the set of peripherals on the 56F8322 and 56F8122 devices.
Peripherals are listed in order of the base address.
