Description
This pin has two functions. At start up, if the pin is
pulled up by a resistor, the PAK3 uses this pin as a
busy indicator. The pin will read 0 when the PAK3 is
not busy. However, if at startup the pin is pulled to
ground, the PAK3 will indicate its busy status on the
Enable/Busy pin.
If Busy/Mode is pulled high at start up, the
Enable/Busy pin is only an input. Bring it low to
disable the PAK3, or high to enable it. However, if
Busy/Mode is pulled low at start up, this pin serves as
an open-collector I/O pin. If the host pulls the pin
low, it disables the PAK3. If the PAK3 is busy, it
pulls the pin low.
The host pulses the CLK pin to shift data in or out of
the PAK3.
The PAK3 reads data from this pin. You may short
SIN and SOUT and use the same pin for input and
output if the host is capable of treating a single pin as
an I/O pin.
The PAK3 writes data to the host on this pin. Since
the pin is open collector, you'll need a resistor to 5V
on this pin. You may short SIN and SOUT together
to use one pin for I/O
Hardware resets the PAK3 when low.
