pass it to the FLoadX (or FLoadY) subroutine.
You can also use the LOADX or LOADY
command directly. The other way you can load a
number is via the FLOAT or FLoadInt commands.
Q: Can I run the Pak II from a different clock
source?
A: Yes. Any crystal or ceramic resonator up to
20Mhz may work. Remember, the ceramic
resonator has capacitors that you will have to
supply if you use a crystal or a resonator without
capacitors. You'll use two capacitors (one on each
RES pin). You'll have to experimentally determine
the values. Start with about 15pf and work up to as
much as 100pf for very low frequency crystals.
You can also feed an existing TTL-level clock
signal into pin 16.
Q: Will running the Pak II at a lower speed reduce
its power consumption? Will it run faster?
A: Yes running at slower speeds will save power.
You will probably not have success overclocking
the Pak II. However, contact AWC for information
on faster devices and other customizations.
Q: Why are my results backwards?
A: Make sure you are using MSBPRE with the
ShiftIn command and not MSBFIRST. Use
MSBFIRST with the ShiftOut command.
