Reset Configuration
RCON
The Serial Flash Programming mode is entered by asserting the
RCON pin (with the TEST pin negated) as the chip comes out of
reset. During this mode, the EzPort has access to the Flash memory
which can be programmed from an external device.

Test
TEST
Reserved for factory testing only and in normal modes of operation
should be connected to VSS to prevent unintentional activation of
test functions.
