Symbol
Function
SPIE
If both SPIE and ES are set to one, SPI interrupts are enabled.
SPE
SPI enable bit.
0: Disables SPI.
1: Enables SPI and connects SS#, MOSI, MISO, and SCK to pins P1.4, P1.5, P1.6, P1.7.
DORD
Data Transmission Order.
0: MSB first in data transmission.
1: LSB first in data transmission.
MSTR
Master/Slave select.
0: Selects Slave mode.
1: Selects Master mode.
CPOL
Clock Polarity
0: SCK is low when idle (Active High).
1: SCK is high when idle (Active Low).
CPHA
Clock Phase control bit.
0: Shift triggered on the leading edge of the clock.
1: Shift triggered on the trailing edge of the clock.
SPR1, SPR0
SPI Clock Rate Select bits. These two bits control the SCK rate of the device
configured as master. SPR1 and SPR0 have no effect on the slave. The relationship
between SCK and the oscillator frequency, fOSC, is as follows:
Symbol
Function
SPIF
SPI Interrupt Flag.
Upon completion of data transfer, this bit is set to 1.
If SPIE =1 and ES =1, an interrupt is then generated.
This bit is cleared by software.
WCOL
Write Collision Flag.
Set if the SPI data register is written to during data transfer.
This bit is cleared by software.
