Description
Port H/CTS input for SCIF1
Though this pin is fixed to input and enters the output Hi-
Z state in the initial state, the internal pull-up MOS is
turned on.
Nonmaskable interrupt request
When this pin is not used, it should be fixed to high.
Port B/external interrupt request input
Though this pin is fixed to input and enters the output Hi-
Z state in the initial state, the internal pull-up MOS is
turned on.
Test pin
This pin must be fixed to low.
Reserved
This pin should be open.
Reserved
This pin should be open.
Analog power supply for D/A converter (DAC) (0 V)
Crystal unit pin
External clock input/crystal unit pin
External clock input/crystal unit pin for Bluetooth power-
down state
When RTCSEL0 = high, this pin enters the non-active
state.
Transmit/receive data I/O for RF IC
The initial state is output.
Clock input for data I/O with RF IC
This pin is always input.
SPI serial data I/O with RF IC
The initial state is output.
D− I/O for on-chip USB transceiver
The initial state is Hi-Z.
D+ I/O for on-chip USB transceiver
The initial state is Hi-Z.
Analog power supply for USB transceiver (0 V)
Power supply for I/O pins with RF IC (0 V)
