Table 15-2. ROM Loader Baud Rates vs. Crystal Frequency

Note: Only a few possible timer reload/PC UART reload values are shown per crystal frequency. This table, by no means, is an exhaustive list of acceptable
configurations for each crystal frequency, nor should it be considered a list of the allowable crystal frequencies.

Table 15-3. Alphabetic Commands

COMMAND

FUNCTION

B

Self-CFC of internal ROM code.

C

CRC-16 of flash memory range (inhibited if either LB2 or LB3 set).

CX

CRC-16 of external RAM range.

D

Dump Intel hex from internal flash memory range.

DX

Dump Intel hex from external RAM range.

K

Klear-Erase entire flash memory range.

L

Load flash memory (Oh–3FFFh).

LB

Load flash memory blindly (Oh–3FFFh)—no verify or precheck.

LE

Load encryption vector (0–3Fh).

Command Line Interface

The ROM loader uses an easy-to-use command line interface that responds to alphabetic commands that are summarized in

Table 15-3. A detailed description of each command can be found in the following pages.
