Description is TEST pin to enable TEST mode. IF this pin is LOW, then test
mode is enabled. For normal usage disable TEST mode by holding this pin
high, or floating. There is an internal 100Kohm pull-up on this pin
Control signal.
If MS pin is LOW, then this pin acts as a priority pin
If MS pin is HIGH, then this pin acts as a port select pin
If pin 30 is LOW, port 1 is chosen
If pin 30 is HIGH, port 2 is chosen Definition of chosen depends on the func-
tion of pin 30. For example, if the function is priority, then chosen means
"chosen as highest priority"
