7734P–AVR–08/10
ACMP1M, Analog Comparator 1 Negative 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.
PCSINr, PSCR Digital Input.
• XTAL1/PSCIN2/ACMP1_OUT – Bit 1
XTAL1: Chip clock Oscillator pin 1. Used for all chip clock sources except internal calibrated RC Oscil-
lator. When used as a clock pin, the pin can not be used as an I/O pin.
PCSIN2, PSC 2 Digital Input.
ACMP1_OUT, Analog Comparator 1 Output.
• RESET/OCD/INT2 – Bit 0
RESET, Reset pin: When the RSTDISBL Fuse is programmed, this pin functions as a normal I/O pin, and
the part will have to rely on Power-on Reset and Brown-out Reset as its reset sources. When the RST-
DISBL Fuse is unprogrammed, the reset circuitry is connected to the pin, and the pin can not be used as an
I/O pin.
If PE0 is used as a reset pin, DDE0, PORTE0 and PINE0 will all read 0.
INT2, External Interrupt source 2. This pin can serve as an External Interrupt source to the MCU.
