The MCF5253 has a number of pins which are multiplexed with both a primary function, a secondary
function, and a GPIO function (triple functionality). Two pins have 3 major functions (a primary and two
secondary functions). Two pins also have their multiplexed functions selected at power-on reset via
external pull-up / pull-down resistors.
At Power-on RESET the primary function (the function listed first in the pin name) is enabled. The GPIO
function is selected as required by setting the appropriate bit in the GPIO-FUNCTION or
GPIO1-FUNCTION registers as described in
To enable the secondary function the appropriate Pin Configuration register bit needs to be set.
Note: in all cases the GPIO FUNCTION register setting has priority. Therefore it is necessary to set the
appropriate GPIO FUNCTION bit to 0 to enable the primary or secondary function.
