In my zeal to eliminate warnings, I added declarations of all ISR
functions to a shared header file. However, I managed to include the
'weak' declaration, which meant that the intended ISR functions were
as weak as the 'default' ISR functions. This left all interrupts
non-functional, which doesn't make for a happy program.

The nvic iser and icer registers read value indicates all enabled
interrupts, icer writes disable the set interrupts. Re-writing icer
with the current value ends up disabling all interrupts, not exactly
what we wanted.

They're amazingly noisy on EasyMini, so just filter them as the only
thing we use them for is battery and pyro numbers.

configure which one it wants.

Set prescale limit, not current prescale value (pr instead of pc).
Flip output 1 on PWM match (set emc toggle for channel 1).
Don't hold counter in reset (turn off CRST bit).

The lpc demo now has a USB command line.
Also allocates system stack so we know when ram is tight at build time
