+ immediately driven to reset state. A brief explanation of why this
+ is important follows.
+
+ At least dsPIC33F and PIC24H --and very likely other 16-bit PIC
+ families-- draw a large amount of current when running, especially
+ when using a fast clock: from 60 mA up to approx. 90 mA. If the
+ PIC target begins to run before the client can request a new ICSP
+ session, which requires much less current (e.g., less than 2 mA),
+ then the MSP430 chip on the GoodFET will fail to start and the FTDI
+ may have trouble communicating with the client. The latter likely
+ relates to the FTDI on-chip 3V3 regulator being specified up to
+ only 50 mA. */
