ATmega16M1/32M1/64M1
• PCINT18/PSCIN2/OC1A/MISO_A, Bit 2
PCSIN2, PSC Digital Input 2.
OC1A, Output Compare Match A output: This pin can serve as an external output for the
Timer/Counter1 Output Compare A. The pin has to be configured as an output (DDD2 set “one”)
to serve this function. The OC1A pin is also the output pin for the PWM mode timer function.
MISO_A: Master Data input, Slave Data output pin for SPI channel. When the SPI is enabled as
a master, this pin is configured as an input regardless of the setting of DDD2. When the SPI is
enabled as a slave, the data direction of this pin is controlled by DDD2. When the pin is forced to
be an input, the pull-up can still be controlled by the PORTD2 bit.
PCINT18, Pin Change Interrupt 18.
• PCINT17/PSCIN0/CLKO – Bit 1
PCSIN0, PSC Digital Input 0.
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 PORTD1 and
DDD1 settings. It will also be output during reset.
PCINT17, Pin Change Interrupt 17.
• PCINT16/PSCOUT0A – Bit 0
PSCOUT0A: Output 0 of PSC 0.
PCINT16, Pin Change Interrupt 16.
