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 56F8335/56F8135 devices do
NOT contain this oscillator.
Part 4 Memory Map
4.1 Introduction
The 56F8335 and 56F8135 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 memories are used in both spaces.
This section provides memory maps for:
Program Address Space, including the Interrupt Vector Table
Data Address Space, including the EOnCE Memory and Peripheral Memory Maps
On-chip memory sizes for each device are summarized in Table 4-1. Flash memories’ restrictions are
identified in the “Use Restrictions” column of Table 4-1.
Note: Data Flash and Program RAM are NOT available on the 56F8135 device.

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