3.1 Pin Descriptions
This section provides a detailed description of each pin. The signals are arranged in functional groups
according to their associated interface.
The “_N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal
is at a low voltage level. For example, RESET_N indicates that the reset signal is active low. When
“_N” is not present after the signal name, the signal is asserted when at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working
with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a
signal is active, independent of whether that level is represented by a high or low voltage. The term
negate, or negation, indicates that a signal is inactive.
Note: The buffer type for each signal is indicated in the BUFFER TYPE column of Table 3.1. A
description of the buffer types is provided in Section 3.3.

DESCRIPTION
USB/HSIC INTERFACES
FLEX_USBUP_DP
AIO Upstream USB Port 0 D+ data signal.
See Note 3.2.
Note:
The upstream Port 0 signals can be
optionally swapped with the
downstream Port 1 signals.
PRT_DIS_P0
IS This strap is used in conjunction with
PRT_DIS_M0 to disable USB Port 0.
0 = Port 0 D+ Enabled
1 = Port 0 D+ Disabled
Note:
Both PRT_DIS_P0 and PRT_DIS_M0
must be tied to VDD33 at reset to place
Port 0 into HSIC mode.
See Note 3.3 for more information on
configuration straps.
FLEX_USBUP_DM AIO Upstream USB Port 0 D- data signal.
See Note 3.2.
Note:
The upstream Port 0 signals can be
optionally swapped with the
downstream Port 1 signals.
PRT_DIS_M0
IS This strap is used in conjunction with
PRT_DIS_P0 to disable USB Port 0.
0 = Port 0 D- Enabled
1 = Port 0 D- Disabled
Note:
Both PRT_DIS_P0 and PRT_DIS_M0
must be tied to VDD33 at reset to place
Port 0 into HSIC mode.
See Note 3.3 for more information on
configuration straps.
