Terminal Functions

The terminal functions table (Table 2-5) identifies the external signal names, the associated pin (ball)

numbers along with the mechanical package designator, the pin type (I, O/Z, or I/O/Z), whether the pin

has any internal pullup/pulldown resistors and a functional pin description. For more detailed information

on device configuration, peripheral selection, multiplexed/shared pins, and debugging considerations, see

Section 3.

GP00/HPI_EN

I/O/Z

IPD

off.

1 = Internal pulls on most HPI IO are disabled and all buffers are

turned on.

For more detail about internal pull options, see Section 3.3.1.

IPD

General-purpose input/output pin [4:2] multiplexed with TSIP[2:0]

internal pulls enable/disable

GP03/TSIP1_EN

I/O/Z

IPD

0 = Internal pulls on TSIPx IO are enabled and buffers are turned

off.

GP04/TSIP2_EN

I/O/Z

IPD

on.

For more detail about internal pull options, see Section 3.3.1.

General-purpose input/output pin 5 multiplexed with EMAC1

internal pulls enable/disable

(1)

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal

(2)

IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-k

Ω IPD or IPU resistor. To pull up a signal to the

opposite supply rail, a 1-k

Ω resistor should be used.)

(3)

IPU/IPD logic on some pins can be disabled based on configuration. For more information, see .
