ASIX Forte - 5.13.3 ICSP Connector

Page 86
Notes
• An error may occur if UP cannot program the
calibration word or if a fault occurs during Device ID
reading, UP warns about an overcurrent at VDD, etc.
This may be eliminated by prolonging the charging/
discharging time in the ▸ Delay for VDD switching on/
off when supplied from programmer option - up to
several seconds.
• If UP points out an overcurrent error at VPP, a shorter
ICSP cable may help (its maximum length is 15cm).
5.13.3 ICSP Connector
All ASIX programmers use a unified connector with
2.54mm spacing of pins for programming with the ICSP
algorithm.
This connector has 8pins with 7signals. Not all signals
are always needed for the programming itself.
For further information on connecting a device to the
programmer see Connection Examples.

Appendix C: Intel‑HEX
File Format
This appendix describes the format of Intel-HEX files used
by UP for data reading and saving. .hex is the typical
extension for such a file.
5.14.1 Supported
Alternatives of HEX
Files
UP supports 2 basic alternatives of Intel-HEX files:
• "basic", sometimes also 8-bit Intel-HEX File (e.g.
Microchip MPASMWIN generates this file with
parameter INHX8M).
• "extended", sometimes also 32-bit Intel-HEX File (e.g.
Microchip MPASMWIN generates this file with
parameter INHX32).
