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