VREF0 is the reference voltage input pin for the A-D0 converter.
VREF1 is the reference voltage input pin for the A-D1 converter.
Hardware trigger input pin to start A-D conversion.
System break interrupt (SBI) input pin for the interrupt
controller
When channel 0 is in UART mode:
This pin outputs a clock derived from BRG output by halving it.
When channel 0 is in CSIO mode:
This pin accepts as its input a transmit/receive clock when external clock
source is selected or outputs a transmit/receive clock when internal clock
source is selected.
When channel 1 is in UART mode:
This pin outputs a clock derived from BRG output by halving it.
When channel 1 is in CSIO mode:
This pin accepts as its input a transmit/receive clock when external clock
source is selected or outputs a transmit/receive clock when internal clock
source is selected.
When channel 4 is in UART mode:
This pin outputs a clock derived from BRG output by halving it.
When channel 4 is in CSIO mode:
This pin accepts as its input a transmit/receive clock when external clock
source is selected or outputs a transmit/receive clock when internal clock
source is selected.
When channel 5 is in UART mode:
This pin outputs a clock derived from BRG output by halving it.
When channel 5 is in CSIO mode:
This pin accepts as its input a transmit/receive clock when external clock
source is selected or outputs a transmit/receive clock when internal clock
source is selected.
Transmit data output pin for serial I/O channel 0
Receive data input pin for serial I/O channel 0
