---------------------------------------------------------
* In the Flash/RAM-test mode
(when the chip is in reset state):
P1.0 and P1.1: A13 and A14 inputs.
* In the functional test mode
(CPU executes out of ext. program memory):
P1.0 and P1.1:
do not output A13 and A14, but function in
their normal operational state.
