Most controllers in the AVR
family support SPI. AVR has 3 register associated with the SPI.
1. SPSR
(SPI Status Register)
2. SPCR
(SPI Control Register)
3. SPDR
(SPI Data Register)

Serial Peripheral Interface Protocol
SPI
– Serial Peripheral Interface is a bus interface used in many peripheral
devices and nowadays almost all microcontrollers have it. Basically it connects
a single masters to multiple slaves. So a single master controller can receive
and transmit data to multiple slave microcontrollers.
