3.2.3
The recommended method of connecting an external clock is given in
source is connected to XTAL and the EXTAL pin is grounded. Set OCCS_COHL bit high when using an
external clock source 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 56F8366/56F8166 devices do
NOT contain this oscillator.
Part 4 Memory Map
4.1 Introduction
The 56F8366 and 56F8166 devices are 16-bit motor-control chip 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 memories are used in both spaces.
This section provides memory maps for:

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.
