Alternate Functions of Port C
The Port C pins with alternate functions are shown in
Table 13-2.
The alternate pin configuration is as follows:
• INT0/ICP0/XTAL - Port C, Bit 0
INT0, External Interrupt 0: When INT0 is written to one and the I-bit in the Status Register
(SREG) is set (one), the corresponding external pin interrupt is enabled. The Interrupt Sense
Control bits in the
whether the external interrupt is activated on rising or falling edge or level sensed. Activity on
any of these pins will trigger an interrupt request even if the pin is enabled as an output. This
provides a way of generating a software interrupt.
XTAL, External Clock: When the CKSEL fuse is programmed, PC0 is used as clock source
instead of the Internal RC oscillator (For test purposes only).
• MOSI/INT1/EXT_PROT - Port C, Bit 1
MOSI, Slave Data Input pin for SPI Programming.
INT1, External Interrupt 1: When INT1 is written to one and the I-bit in the Status Register
(SREG) is set (one), the corresponding external pin interrupt is enabled. The Interrupt Sense
Control bits in the
whether the external interrupt is activated on rising or falling edge or level sensed. Activity on
any of these pins will trigger an interrupt request even if the pin is enabled as an output. This
provides a way of generating a software interrupt.
EXT_PROT, External Protection Input: When the EPID bit in the BPCR Register is cleared,
the External Protection Input functionality is enabled. Note that this port overriding is default
enabled.
