Input/Output Description
A-D converter
AVCC0,
Analog power supply –
AVCC0 and AVCC1 are the power supply for the A-D0 and
AVCC1
the A-D1 converter, respectively. Connect AVCC0 and AVCC1
to the power supply rail.
AVSS0,
Analog ground
–
AVSS0 and AVSS1 are the analog ground for the A-D0 and
AVSS1
the A-D1 converter, respectively. Connect AVSS0 and AVSS1
to ground.
AD0IN0
Analog input
Input
16-channel analog input pins for the A-D0 converter, i.e.,
–AD0IN15
the first block A-D converter.
AD1IN0
Analog input
Input
16-channel analog input pins for the A-D1 converter, i.e.,
–AD1IN15
the second block A-D converter.
VREF0,
Reference voltage
Input
VREF0 and VREF1 are the reference voltage input pin for
VREF1
input
the A-D0 and the A-D1 converter, respectively.
Interrupt
SBI#
System break
Input
This is the system break interrupt (SBI) input pin for the
controller
interrupt
interrupt controller.
Serial I/O
SCLKI0/
UART transmit/receive Input/output
When channel 0 is in UART mode:
SCLKO0
clock output or CSIO
This pin outputs a clock derived from BRG output by
transmit/receive clock
dividing it by 2.
input/output
When channel 0 is in CSIO mode:
This pin accepts as input a transmit/receive clock when
external clock is selected or outputs a transmit/receive
clock when internal clock is selected.
SCLKI1/
UART transmit/receive Input/output
When channel 1 is in UART mode:
SCLKO1
clock output or CSIO
This pin outputs a clock derived from BRG output by
transmit/receive clock
dividing it by 2.
input/output
When channel 1 is in CSIO mode:
This pin accepts as input a transmit/receive clock when
external clock is selected or outputs a transmit/receive
clock when internal clock is selected.
SCLKI4/
UART transmit/receive Input/output
When channel 4 is in UART mode:
SCLKO4
clock output or CSIO
This pin outputs a clock derived from BRG output by
transmit/receive clock
dividing it by 2.
input/output
When channel 4 is in CSIO mode:
This pin accepts as input a transmit/receive clock when
external clock is selected or outputs a transmit/receive
clock when internal clock is selected.
SCLKI5/
UART transmit/receive Input/output
When channel 5 is in UART mode:
SCLKO5
clock output or CSIO
This pin outputs a clock derived from BRG output by
transmit/receive clock
dividing it by 2.
input/output
When channel 5 is in CSIO mode:
This pin accepts as input a transmit/receive clock when
external clock is selected or outputs a transmit/receive
clock when internal clock is selected.
