Execution mode
When the E2PROM is connected to ports P4.2 and P4.3 or P3.6 and P3.7, the boot-
loader works automatically in execution mode. At reset, it transfers the code from the
E2PROM to the internal CRAM (volatile program memory) and execute it. The E2PROM
must contain a valid code. As the bootloader does not support E2PROM programming
functions, the E2PROM must be programmed by external programmer or by a specific
code which is programmed in CRAM and which behaves as a bootloader. This code
programs the E2PROM by the code received from FLIP.
RS232C
DEMO BOARD CONFIGURATION
- Set the POWER switch in OFF position
- Remove any USB cable connected to demoboard
- Remove any E2P present on DIP socket
- Configure the power jumper accordingly to power source wich supplies the demo board
- Connect a RS232C cable between demo board and PC
- Set the POWER switch in ON position
-->
Result
: PWR ON and ALE leds are switched on
-->
Trouble shooting
: check if 8 Mhz quartz is correctly fitted
PROGRAMMING PART
- Run FLIP
- Select part at8xc5122 for FLIP 1.8.8 or part at8xc5122_dpw for FLIP 2.x.x
- Select a RS232C communication
- Establish a serial communication with the appropriate COM number and a baudrate comprised
between 1200 and 38400 .
