4.6.5 Pin State During Reset
4.6.5.1 Reset States of SIM Pins
4-42
It is important to keep the distinction between pin function and pin electrical state clear.
Although control register values and mode select inputs determine pin function, a pin
driver can be active, inactive or in high-impedance state while reset occurs. During
power-up reset, pin state is subject to the constraints discussed in 4.6.7 Power-On
Reset.
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 during reset
become active high-impedance loads after RESET is released. Inputs must be driven
to the desired active state. Pull-up or pull-down circuitry may be necessary. Pins con-
figured as outputs begin to function after RESET is released. Table 4-18 is a summary
of SIM pin states during reset.

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.
