the OCCS_COHL bit high as well.
3.3 Registers
When referring to the register definitions for the OCCS in the 56F8300 Peripheral User Manual, use the
register definitions without the internal Relaxation Oscillator, since the 56F8367/56F8167 do NOT
contain this oscillator.
Part 4 Memory Operating Modes (MEM)
4.1 Introduction
The 56F8367 and 56F8167 devices are 16-bit motor-control chips based on the 56800E core. These parts
use a Harvard-style architecture with two independent memory spaces for Data and Program. On-chip
RAM and Flash memory are used in both spaces.
This chapter provides memory maps for:
On-chip memory sizes for each device are summarized in
identified in the “Use Restrictions” column of
Note: Data Flash and Program RAM are NOT available on the 56F8167 device.

Note: When using an external clocking source with
this configuration, the input “CLKMODE” should be
high and the COHL bit in the OSCTL register
should be set to 1.
