The mask ROM versions (

µ

PD78052Y, 78053Y, 78054Y, 78055Y, 78056Y, 78058Y) 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

PD78054Y subseries are shown in Table 2-1.
