PD780343, 780344, 780353, 780354, 780343Y, 780344Y, 780353Y, and 780354Y)
provide pull-up resistor mask options which allow users to specify whether to connect a pull-up resistor to a specific
port pin when the user places an order for device production. Using the mask option when pull-up resistors are required
reduces the number of components to add to the device, resulting in board space saving.
The mask options provided in the
