MPSSE mode instructions to set / clear or read the high
byte of data can be used with this pin. *Note
MPSSE mode instructions to set, clear or read the high
byte of data can be used with this pin. Additionally, this
pin has instructions that will make the controller wait until
it is high, or wait until it is low. This can be used to
connect to an IRQ pin of a peripheral chip. The
DLP2232M will wait for the interrupt, and then read the
device, and pass the answer back to the host PC. I/O1 must
be held in input mode if this option is used. *Note
Extends the time taken to perform a Read or Write
operation if pulled low. Pull up to Vcc if not being used.
