3.7.2 MCU Module Pin Function During Reset
MC68331
USER’S MANUAL
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 sections in this manual for more infor-
mation. Table 3-7 is a summary of module pin function out of reset.
