ISP for P89LPC932 RevC

Hi all!
I have P89LPC932 Rev C, and I can\'t reprograme using ISP again, I using FlashMagic to load hex file from example Hello to micro, but then, micro can\'t enter ISP again, although I send BootLoader <89LPC932AppNote>.
In example, I see that: BSB=1, BOE=1, RPE=1.
Can you give any advice? Thanks before!

Some first P89LPC932 versions had problems with ISP (see Philips
site). P89LPC932A1 is fixed version and I have no problems with it.
It is also possible to owerwrite ISP code if you set wrong
FlashMagic parameters; that way you can't use ISP again. You can
still enter the program using ICP. If ISP code is lost (owerwritten)
you must program it by ICP again.

What is written on your chip exactly ?

Maybe I have met the problem with ISP circuit, can you give me a ICP circuit? Thanks before!

It is possible to made ISP circuit because it is quite simple, but
ICP circuit is beyond my knowledge. I sugest you to use some of ICP
programmer devices out there. I'm using EPM900 from Keil Software.

P89LPC932 revC 't support enter ISP by Hardware (3 pulse reset), and in datasheets, this micro isn't support for ICP.
