Table 1.3.1 Description of Pin Functions (3/5)
Type Pin Name Signal Name 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.
