ATmega32/64/M1/C1

MISO, 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 DDB0. When the SPI is

enabled as a slave, the data direction of this pin is controlled by DDB0. When the pin is forced to

be an input, the pull-up can still be controlled by the PORTB0 and PUD bits.

PSCOUT2A, Output 2A of PSC.

PCINT0, Pin Change Interrupt 0.

Table 9-4 and Table 9-5 relates the alternate functions of Port B to the overriding signals shown

in Figure 9-5 on page 65.
