Hi,

I'm trying to program a LPC1114LV using the ISP and UART interface and finding that when the UART communicates it's LOW or zeros are infact around 0.6mV.  Is this normal?

It's causing all sorts of headaches with various serial connectors that seem to think anything above 0.3mv is a 1.

Cheers
