Users Wish: extend RSTON pulse
Addition of RSTOLONGN: this is the same function as RSTON but it is a pulse of 2ms.
Ben Todd explains: Allows the reset output to be connected to analogue
circuitry on our main board.
200ns pulse is quite short for our application, so we have risk of SEU
leading to spurious power cycles, and have quite a short RC-filter on
the signal.
Could also be implemented as external hardware, but could mean
additional logic which may not be used elsewhere in the design,
may need to be qualified in radiation.
Suggested RSTOLONGN pin: 95
