Serial Peripheral Interface (SPI)
8.7 SPI Registers
8.7.1 Serial Peripheral Control Register
Data Sheet
138
The three SPI registers are:
These registers provide control, status, and data storage functions.
SPIE — Serial Peripheral Interrupt Enable Bit
SPE — Serial Peripheral System Enable Bit
DWOM — Port D Wired-OR Mode Bit
MSTR — Master Mode Select Bit
•
•
•
Set the SPE bit to 1 to request a hardware interrupt sequence each time the
SPIF or MODF status flag is set. SPI interrupts are inhibited if this bit is clear or
if the I bit in the condition code register is 1.
When the SPE bit is set, the port D bit 2, 3, 4, and 5 pins are dedicated to the
SPI function. If the SPI is in the master mode and DDRD bit 5 is set, then the
port D bit 5 pin becomes a general-purpose output instead of the SS input.
DWOM affects all port D pins.
It is customary to have an external pullup resistor on lines that are driven by
open-drain devices.
