the result will be in IEEE format. If you
execute an INT command, the exponent
will be meaningless, and the mantissa will
be the 24 bit binary integer result.
RIO
This command reads 8 bits from the I/O
port. Of course, bits set to outputs will read
whatever you are writing to them. The Pak
sends the byte immediately.
STO0, STO1
Stores X in register 0 or 1.
SUB
Computes X-Y leaving the result in X. Y is
unchanged. This command may take
approximately 110uS in the worst case.
SWAP
Swaps X and Y
WIO
This command writes 8 bits to the I/O port.
This only affects pins that are set as
outputs. Send the byte immediately after
the command.
XTOY
Stores X in Y without changing X.
YTOX
Stores Y in X without changing Y.
