Throughout this manual, the registers are discussed by function. In the
event that not all bits in a register are referenced, the bits that are not
discussed are shaded.
SPIE — Serial Peripheral Interrupt Enable Bit
SPE — Serial Peripheral System Enable Bit
DWOM — Port D Wired-OR Mode Bit
MSTR — Master Mode Select Bit

DWOM affects only the four SPI pins on port D, PD[5:2]. See also
7.9.2 Serial Communications Control Register 1
of the WOMS (wired-OR Mode for SCI pins) bit in the serial
communications control register 1 (SCCR1).
