7710E–AVR–08/10
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.
• PSCOUT00/XCK/SS_A – Bit 0
PSCOUT00: Output 0 of PSC 0.
XCK, USART External clock. The Data Direction Register (DDD0) controls whether the clock is
output (DDD0 set) or input (DDD0 cleared). The XCK0 pin is active only when the USART oper-
ates in Synchronous mode.
SS_A: Slave Port Select input. When the SPI is enabled as a slave, this pin is configured as an
input regardless of the setting of DDD0. 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 DDD0.
When the pin is forced to be an input, the pull-up can still be controlled by the PORTD0 bit.
