Description
Serial data I/O (N-channel open drain output).
Transmit/receive clock I/O (N-channel open drain output).
Output used for D+ 1.5 kΩ pull-up
Input the power supply signal from a host PC
Input power supply for pins ATTACH, D+, and D-
USB D+ input/output
USB D- input/output
Reference voltage input for the A/D and D/A converters.
Analog input.
External trigger input.
Extended analog input.
Output for the D/A converter.
VCC2
8-bit CMOS I/O ports. A direction register determines whether
each pin is used as an input port or an output port. A pull-up
resistor may be enabled or disabled for input ports in 4-bit
units.
VCC1
8-bit I/O ports having equivalent functions to P0. However,
P7_0, P7_1, and P8_5 are N-channel open drain output ports.
No pull-up resistor is provided. P8_5 is an input port for
verifying the NMI pin level and shares a pin with NMI.
