2.9 Mask Options
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.
