PD78058FY SUBSERIES)
2.10 Mask Options
The mask ROM versions (
µ
PD78056FY, 78058FY) 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 the device
production. Using this 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
µ
PD78058FY Subseries are shown in Table 2-2.
