5.7.5 Pin State During Reset

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-on reset, pin state is subject to the constraints discussed in 5.7.7 Power-On

Reset.

NOTES:

1. Module port pins may be in an indeterminate state for up to 15 milliseconds at

power-up.
