SPI data I/O register (SPIDR)
The SPIDR register is used to transmit and receive data on the serial bus. In a master
device, a write to this register will initiate transmission/reception of another byte.
During the last clock cycle the SPIF bit is set, a copy of the received data byte in the shift
register is moved to a buffer. When the user reads the serial peripheral data I/O register, the
buffer is actually being read.
While the SPIF bit is set, all writes to the SPIDR register are inhibited until the SPICSR
register is read.
A read to the SPIDR register returns the value located in the buffer and not the content of
the shift register (see

R/W
This bit is set and cleared by software. When set, it disables the alternate function of
the SPI output (MOSI in master mode / MISO in slave mode).
0: SPI output enabled (if SPE = 1).
1: SPI output disabled.
This bit is set and cleared by software. When set, it disables the alternate function of
the SPI SS pin and uses the SSI bit value instead. See
page
0: Hardware management (SS managed by external pin).
1: Software management (internal SS signal controlled by SSI bit. External SS pin
free for general-purpose I/O).
This bit is set and cleared by software. It acts as a ‘chip select’ by controlling the
level of the SS slave select signal when the SSM bit is set.
0: Slave selected.
1: Slave deselected.
