Hi, all ;- Any thoughts on whether an external reset chip adds anything in terms of reliability of start-up, given that the internal BOR circuit will be enabled. Vdd will probably be 5.0V nominal. I'd like to avoid the cost if it adds nothing and to avoid the issue of high voltage (VIHH) on /MCLR during ISP. Best regards, Spehro Pefhany --"it's the network..."
