[1]
Symbol names with an overscore (e.g. 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
F) to all the supply pins. For better EMI results, add a 0.01 F
capacitor in parallel to the 0.1
F.
[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.

I
wake-up input (edge triggered); a LOW-to-HIGH transition
generates a remote wake-up from ‘suspend’ state.

-
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
