I
digital ground
WAKEUP
62
wake-up input (edge triggered); a LOW-to-HIGH transition
generates a remote wake-up from ‘suspend’ state.
input pad; TTL with hysteresis; with internal pull-down
resistor; 5 V tolerant; internal pull-down resistor.

test output; this pin is used for test purposes only
[3]
VCC(3.3)
supply voltage (3.3 V ± 0.3 V); supplies internal digital
circuits or it is the tapped out voltage from the internal
regulator; this regulated voltage cannot be used to drive
external devices; see Section 10
[1] Symbol names with an overscore (for example, NAME) represent active LOW signals.
[2] All outputs and I/O pins can source 4 mA of current.
[3] Add a decoupling capacitor (0.1 µF) to all the supply pins. For better EMI results, add a 0.01 µF
capacitor in parallel to the 0.1 µF.
[4] The DMA bus is in three-state until a DMA command (see Section 9.4.1) is executed.
[5] The control signals are not three-state.
