truncated 16bit timer registers

Pete9:
Oddly it's setting the WGM13 bit that does the magic, not the clock select bits. Not sure what's going on there.

Set the WGM13 bit in register TCCR1B and you'll be able to write a 16 bit value directly to the compare registers

TCCR1B = _BV(WGM13);
OCR1B = 0x0200;

@Pete9

BIG thanks for that bit of insight! I am trying to understand why it is not more widely known and documented and whether it is a hardware thing or a software/IDE thing.
