Pins and Connections
2.1.3
The MCF51EM256 series will be available in 80-pin LQFP and 100-pin LQFP package options.
Table 2-1
“Default Function” column specifies the function of the given pin upon exiting the reset state. Alternate
functions 1, 2 and 3 can be assigned to each pin under software control via the MC
RGPIO_ENB register is used to select between GPIO and RGPIO functions on pins that have both.
Pins not available on smaller packages are automatically disabled for reduced current consumption. No
user interaction is needed. Software access to the functions on these pins will be ignored
