11.6.3.2 Slave Select Management
As an alternative to using the SS pin to control the
Slave Select signal, the application can choose to
manage the Slave Select signal by software. This
is configured by the SSM bit in the SPICSR regis-
ter (see
In software management, the external SS pin is
free for other application uses and the internal SS
signal level is driven by writing to the SSI bit in the
SPICSR register.
In Master mode:

In Slave Mode:
There are two cases depending on the data/clock
timing relationship (see
If CPHA=1 (data latched on 2nd clock edge):
If CPHA=0 (data latched on 1st clock edge):

– SS internal must be held low during the entire

transmission. This implies that in single slave
applications the SS pin either can be tied to

byte to allow the slave to write to the shift reg-
ister. If SS is not pulled high, a Write Collision
error will occur when the slave writes to the
shift register (see
