We are using the LPC952 in several designs. Sometimes we get boards back with the Boot status register altered.
According to NXP this can happen during a brown out condition and can be prevented by setting the CWP bit in the Boot status register
We would like to write/read those bits from Flash Magic, but they are not accessible. The menu selection under ISP for "Additional Security bits.." is grayed out for the LPC952.
Also it seems there is no access to UCFG2 register.
I am using version 3.61.230
Also we are using FDI's USB-ICP dongle for programming. It would be nice to be able to put the LPC952 into ICP mode, one would think this should be able to do since the name already implies it.
So this is what I'd like to see:
access to all Boot status bits
access to UCFG2 register
ICP capability
