Preliminary
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 4-9 summarizes base addresses for the set of peripherals on the 56F8345 and 56F8145 devices.
Peripherals are listed in order of the base address.
The following tables list all of the peripheral registers required to control or access the peripherals.
Note: Features in italics are NOT available in the 56F8145 device.
