NOTE:
Low power and small PCB footprints are critical for certain applications.
Therefore, input pins not used must be pulled high using internal pull-ups
to avoid floating nodes and the need for external pull-up resistors. Unused
pins may also be tied to an external appropriate logic voltage level (for
example, either VDD or GND). Weak pull-ups are available internally on
all IO and BB pins (100k ohms typical case), pull-downs are available on
RESET_BB, TCK, TRST_B pins. Internal level-shifters are used to
accommodate the difference between BB and IO voltages. This provides
glueless interface to peripherals.
4.1 Pin Assignment Listing
The following table (Table 9) shows the pin assignment listing for the MC72000 IC. The pins are
organized into functional groups.
The Pin Name and Functionality columns show the actual name and a brief description of each pin,
with respect to the ball assignment in the column Ball #.
The Power Group column lists the Supply Power Group assignment.
The Pin Type column shows the type of internal circuitry to the chip.
The Reset State column lists the pin input/output direction at chip RESET_BB.
The Alternate Function column lists each of the GPIO port alternate input and output selections
available. Some selections are test- or development-mode specific.
