Can I use IAP routines with PLL multiplier other than 1x.

2005-08-27 by lhaddix

Hi,
Does anyone know if you can use the IAP routines
on an LPC2138 to write the flash while running
at crystal x6. I saw a note somewhere that said
you had to drop the clock multiplier to 1x to use
the IAP, but only prior to a certain version.

Has anyone tried this?

The Phillips boot loader gives evidence that you
must run at 1x because it can't go past 19200 baud
with 11.0592mhz. However the IAP routines may not
care what the multiplier is and it's just how the
bootloader sets up the PLL.
