13.3.3 SS Output
Available in master mode only, SS output is enabled with the SSOE bit in the SP0CR1 register if the
corresponding DDRS bit is set. The SS output pin will be connected to the SS input pin of the external
slave device. The SS output automatically goes low for each transmission to select the external device
and it goes high during each idling state to deselect external devices.
13.3.4 Bidirectional Mode (MOMI or SISO)
In bidirectional mode, the SPI uses only one serial data pin for external device interface. The MSTR bit
decides which pin to be used. The MOSI pin becomes serial data I/O (MOMI) pin for the master mode,
and the MISO pin becomes serial data I/O (SISO) pin for the slave mode. The direction of each serial
I/O pin depends on the corresponding DDRS bit.
Figure 24 Normal Mode and Bidirectional Mode
13.3.5 Register Descriptions
Control and data registers for the SPI subsystem are described below. The memory address indicated
for each register is the default address that is in use after reset. The entire 512-byte register block can
be mapped to any 2-Kbyte boundary within the standard 64-Kbyte address space. For more information
refer to
