PAK-II Datasheet, PDF (20/28 Pages) List of Unclassifed Manufacturers – 310 Ivy Glen Court

TAN/ATAN
Sets the X register to the tangent/arctangent
of X (in radians).
WIOA/B
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.
Typical Circuits and Software
Connecting the Pak-II to its external components is
simple. Supply 5V to Vdd and ground the Vss
pins. Connect the two outer pins of the ceramic
resonator to the RES1 and RES2 pins (the order
does not matter). Ground the center pin of the
resonator. Connect the RESET pin to 5V. For the
simplest mode of operation connect the ENABLE/
BUSY pin to 5V and the BUSY/MODE pin to 5V
through a pull up resistor (10K-22K). Of course,
you'll also need to make connections to the host
microprocessor. You may also want to make
different connections to ENABLE/BUSY and
BUSY/MODE if you want to use different
methods of synchronizing.
