The following sections discuss areas to consider when the MSC8144 device is designed into a system.
3.1
3.1.1
Use the following guidelines for power-on sequencing:
External voltage applied to any input line must not exceed the related to this port I/O supply by more than 0.6 V at any time,
including during power-up. Some designs require pull-up voltages applied to selected input lines during power-up for
configuration purposes. This is an acceptable exception to the rule during start-up. However, each such input can draw up to 80
mA per input pin per MSC8144 device in the system during start-up. An assertion of the inputs to the high voltage level before
power-up should be with slew rate less than 4 V/ns.
