• Manufacturer Part Number: at90pwm81-16se
• Description: 8-bit Avr Microcontroller With 8k Bytes In- System Programmable Flash
• Manufacturer: ATMEL Corporation

7734M–AVR–03/10
ADC1, Analog to Digital Converter, input channel 1.
ACMP2_OUT, Analog Comparator 2 Output.
• ADC0/ACMP1, Bit 2
ADC0, Analog to Digital Converter, input channel 0
ACMP1, Analog Comparator 1 Positive Input. Configure the port pin as input with the internal pull-up
switched off to avoid the digital port function from interfering with the function of the Analog
Comparator.
• PSCOUTR0/PSCINrB – Bit 1
PSCOUTR0: Output 0 of PSCR.
PCSINrB, PSCR Second Alternate Digital Input.
• ACMP3_OUT_A/SS/CLKO – Bit 0
ACMP2_OUT_A, Analog Comparator 2 Alternate Output.
SS: Slave Port Select input. When the SPI is enabled as a slave, this pin is configured as an input regard-
less of the setting of DDDn. As a slave, the SPI is activated when this pin is driven low. When the SPI is
enabled as a master, the data direction of this pin is controlled by DDDn. When the pin is forced to be an
input, the pull-up can still be controlled by the PORTDn bit.
CLKO, Divided System Clock: The divided system clock can be output on this pin. The divided system
clock will be output if the CKOUT Fuse is programmed, regardless of the PORTDn and DDDn settings. It
will also be output during reset.
