PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Package Description
Notes:
1
Place pull-up resistors of 120 Ohms or less on the TEST[0–1] pins.
2
Treat these pins as No Connects unless using debug address functionality.
3
This pin has an internal pull-up resistor which is enabled only when the MPC8240 is in the reset state.
The value of the internal pull-up resistor is not guaranteed, but is sufcient to insure that a '1' is read into
conguration bits during reset.
4
This pin is a reset conguration pin.
5
DL[0] is a reset conguration pin and has an internal pull-up resistor which is enabled only when the
