SPI Control Register
IRQE
7
The SPI Control Register configures the SPI for transmit and receive operations.
IRQE—Interrupt Request Enable
0 = SPI interrupts are disabled. No interrupt requests are sent to the Interrupt Controller.
1 = SPI interrupts are enabled. Interrupt requests are sent to the Interrupt Controller.
STR—Start an SPI Interrupt Request
0 = No effect.
1 = Setting this bit to 1 also sets the IRQ bit in the SPI Status Register to 1. Setting this
BIRQ—BRG Timer Interrupt Request
If the SPI is enabled, this bit has no effect. If the SPI is disabled:
0 = BRG timer function is disabled.
1 = BRG timer function and time-out interrupt are enabled.
PHASE—Phase Select
Sets the phase relationship of the data to the clock. For more information on operation of
the PHASE bit, see
CLKPOL—Clock Polarity
0 = SCK idles Low (0).
1 = SCK idle High (1).
WOR—Wire-OR (Open-Drain) Mode Enabled
0 = SPI signal pins not configured for open-drain.
1 = All four SPI signal pins (SCK, SS, MISO, MOSI) configured for open-drain function.
This setting is typically used for multi-master and/or multi-slave configurations.
MMEN—SPI MASTER Mode Enable
0 = SPI configured in SLAVE mode.
1 = SPI configured in MASTER mode.
SPIEN—SPI Enable
0 = SPI disabled.
1 = SPI enabled.
bit forces the SPI to send an interrupt request to the Interrupt Control. This bit can
be used by software for a function similar to transmit buffer empty in a UART.
Writing a 1 to the IRQ bit in the SPI Status Register clears this bit to 0.
