Documentation Changes
1.
Changed: Change Section 12.4.2, 3.3V/V5REF Sequencing
Change the third paragraph to read:
As an additional consideration, during suspend, the only signals that are 5 V tolerant capable are
USB OC:[3:0]#. If these signals are not needed during suspend, V5REF_SUS can be connected to
either VccSus3_3 or 5 V_Always/5V_AUX. If OC:[3:0]# is needed during suspend and 5 V
tolerance is required then V5REF_SUS should be connected to 5V_Always/5V_AUX, but if 5 V
tolerance is not needed in suspend, then V5REF_SUS can be connected to either VccSus3_3 or
5V_Always/5V_AUX rails.
2.
Changed: Change Section 14.8, Power and Ground, V5REF_SUS
Change the second bullet in the description of V5REF_SUS to read:
V5REF_SUS only affects 5 V-tolerance for USB OC:[3:0]# pins and can be connected to
either VccSUS3_3 or 5V_Always/5V_AUX if 5V tolerance on these OC:[3:0]# is not
needed. If 5V tolerance on OC:[3:0]# is needed then V5REF_SUS USB must be connected to
5V_Always/5V_AUX which remains powered during S5.
