I'm having a few problems with spurious timer values being reported
by the input captures on my HC11A1FN (EVB). The chip is set up so
that output compare 1 triggers the three input captures at varying
times. The IC value are then copied out into RAM. The problem is this:

when the IC triggering is very close to the OC1 switching, the IC values
(in one of the 3 ICs anyway,) don't change.

i.e.: (see the drawing below:)

				________   _______
OC1 (active low pulse):			|_|

ICx input			________________   ____
 (triggering on falling edge:			|_|

ICx triggered at point T:	.................T.....


Difference in times:			|-- d --|


When <d> becomes very small, the value from the input capture being
tested 'freezes'; it stops at a value and doesn't change. It seems
to work fine when <d> is fairly long, and <d> is different for each
input capture.

Is the chip stuffed? (worst fears :-< )
or is there something else not quite as serious that I've overlooked ( :-| )

Any help PLEASE!!!
