Register Description
SPCR – SPI Control Register
Figure 18-3. SPI Transfer Format with CPHA = 0
Figure 18-4. SPI Transfer Format with CPHA = 1
• Bit 7 – SPIE: SPI Interrupt Enable
This bit causes the SPI interrupt to be executed if SPIF bit in the SPSR Register is set and the if
the Global Interrupt Enable bit in SREG is set.
• Bit 6 – SPE: SPI Enable
When the SPE bit is written to one, the SPI is enabled. This bit must be set to enable any SPI
operations.
