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
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 on the 56F8157 device.
