DESCRIPTION
The X68C64 SLIC E
2
is a highly integrated E
2
Microcontroller peripheral which combines the func-
tionality of the X68C64 component with pre-loaded
software routines allowing any embedded system
using it to upgrade and download software via the
serial port. This self-loading integrated code elimi-
nates the need to initially program the firmware into a
memory device at the time of initial manufacture. The
SLIC E
2
routines also greatly facilitate the loading of
subsequent versions of the firmware into the system.
The SLIC E
2
routines consist of approximately 500
bytes of instructions for the 68HC11 which will ini-
tialize the microcontroller and its on-board UART
and upload the user’s software through the UART.
The baud rate for the transfer is 9600 based on a
crystal frequency of 8MHz. Data transfer is accom-
plished using a proprietary format called XCOM.
Xicor also has developed a program for IBM PCs
and compatibles called XSLIC, which will translate
an Intel HEX or Motorola S-record format file into
XCOM format and download the program to a X68C64
