Thanks for the inputs from Pascula Lopez & Roland.

Hi, floks

1) I don't have very large applications to deal with, so can I stick with Assembly programming with this MCU, old timer assember like the Metalink ASM51. Provided I can manage the 932 header file.

2) Does the Asm51 produce the same 8051 source code which is good for the PLC932?

I just can't afford thousand bulks for a C compiler just for hobby purposes.


Please advice.

Hi there,

I'm a MCU hobbyist recently interested in P89PLC932. My first job is to study how to program the chip for my own application.

Question is, why Philips has to classify the Parallel Programming of the chip? What happened if I accidentially erased/overwritten the ISP or I don't have a mechanism to return to the ISP mode from my application?

Does it means the chip is toasted? Or how I can get back to the ISP mode to reprogram the chip?

Please advice.
