NOTE : for Philips Flash utility


The Philips LPC2000 Flash utility utilizes two, otherwise unused, signals (RTS and DTR) of the PC serial port to control the microcontroller reset and P0.14 pins. The port pin P0.14, if LOW during reset, puts the microcontroller into In System Programming (ISP) mode; this pin has the alternate functions of external interrupt one and general purpose I/O (GPIO). Some details on the associated circuitry will help in understanding how this works.
