3.7.2 Functions of Pins for Other Modules During Reset
MC68332
MC68332TS/D
Generally, pins associated with modules other than the SIM default to port functions, and input/output
ports are set to input state. This is accomplished by disabling pin functions in the appropriate control
registers, and by clearing the appropriate port data direction registers. Refer to individual module sec-
tions in this manual for more information. The following table is a summary of module pin function out
of reset.
