PARAMETER
All leakage currents are measured with pins in high impedance.
Standby Power Requirements
This includes only signals that are outputs and source standby current (no OD outputs). Internal pull-ups
are ignored due to their small contribution. External pull-ups are not in this analysis because they do not
cause LPC47M182 to draw a discernable amount of additional power.
