5.7.5.1 Reset States of SIM Pins
5.7.5.2 Reset States of Pins Assigned to Other MCU Modules
5-54
Generally, while RESET is asserted, SIM pins either go to an inactive high-impedance
state or are driven to their inactive states. After RESET is released, mode selection
occurs, and reset exception processing begins. Pins configured as inputs must be
driven to the desired active state. Pull-up or pull-down circuitry may be necessary. Pins
configured as outputs begin to function after RESET is released.
mary of SIM pin states during reset.
As a rule, module pins that are assigned to general-purpose I/O ports go into a high-
impedance state following reset. However, during power-on reset, module port pins
may be in an indeterminate state for a short period. Refer to
for more information.

Pins that are not used should either be configured as outputs, or (if
configured as inputs) pulled to the appropriate inactive state. This de-
creases additional I
ply level.
