ISP connector
Philips P87LPC76x microcontrollers
This interface corresponds with Philips application note AN466:
In-system
microcontrollers. This application note describes requirement
for target system with In-system programming device and ISP
programmer.
Following signals are use for In-system programming of
P87LPC76x microcontrollers.
When P87LPC76x device is programmed, pin RST\ / VPP is
driven to approximately 10.75V. Therefore, the target system
must be isolated from this voltage provided by programmer.
P0.4 and P0.5 signals are used by the P87LPC76x for In-
system programming, therefore target system mustn’t affect
these signals during In-system programming to avoid
programming errors.
