PA3 or
WU2
I/O/Z
I
Multiplexed pin whose function is selected by:
(PA3) WAKEUP.7 and OEA.3
PA3 is a bidirectional I/O port pin.
WU2 is an alternate source for USB Wakeup, enabled
by WU2EN bit (WAKEUP.1) and polarity set by
WU2POL (WAKEUP.4). If the 8051 is in suspend and
WU2EN = 1, a transition on this pin starts up the oscil-
lator and interrupts the 8051 to enable it to exit the
suspend mode. Asserting this pin inhibits the chip from
suspending, if WU2EN = 1.
