DMA Request, active low. A 10 KΩ pull-up resistor
is required if this pin drives an input. A 10 KΩ pull-
up resistor is recommended even if this pin is not
used.
Interrupt Request, active low. A 10 KΩ pull-up
resistor is required if this pin drives an input. A 10
KΩ pull-up resistor is recommended even if this pin
is not used.
Deep Power-Down. Used to enter and exit Deep
Power-Down mode. This pin is assigned A0
instead of DPD when working in 8-bit mode.
Device core power supply. Requires a 10 nF and
0.1 µF capacitor.
I/O power supply. Sets the logic 1 voltage level
range of I/O pins. VCCQ may be either 2.5V to
3.6V or 1.65V to 2.0V. Requires a 10 nF and
0.1 µF capacitor.
Ground. All VSS pins must be connected.
Reserved. All reserved signals are not connected
internally and must be left floating to guarantee
forward compatibility with future products.
