PAK-II Datasheet, PDF (19/28 Pages) List of Unclassifed Manufacturers – 310 Ivy Glen Court

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.
ROOT
Use this command to calculate roots. For
example, to find the cube root of 10, store
10 in X, 3 in Y, and use the ROOT
command. The SQRT command is much
faster for square roots.
SIN/ASIN
Sets the X register to the sine/arcsine of X
(in radians).
SQRT
This command calculates the square root of
X.
STO
Stores X in the specified register (0-23).
SUB
Computes X-Y leaving the result in X. Y is
unchanged. This command may take
approximately 55uS in the worst case.
SWAP
Swaps X and Y
