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
CO MM A ND FUN C TION
B Self- CFC of internal ROM code.
C CRC -16 of flash memory range ( inhibited if either LB2 or LB3 set).
C X C RC -16 of external RAM range.
D Dum p Intel hex from internal flash memory range.
D X D um p Intel hex from external RAM range.

LB Load flash memory b l indly (Oh–3FFFh)—no verify or p recheck.
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.
