Symbol
SPIE
SPE
Function
If both SPIE and ES are set to one, SPI interrupts are enabled.
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.
Data Transmission Order.
0: MSB first in data transmission.
1: LSB first in data transmission.
Master/Slave select.
0: Selects Slave mode.
1: Selects Master mode.
Clock Polarity
0: SCK is low when idle (Active High).
1: SCK is high when idle (Active Low).
Clock Phase control bit.
0: Shift triggered on the leading edge of the clock.
1: Shift triggered on the trailing edge of the clock.
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, f
OSC
, is as follows:
DORD
MSTR
CPOL
CPHA
SPR1, SPR0
Symbol
SPIF
Function
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.
Write Collision Flag.
Set if the SPI data register is written to during data transfer.
This bit is cleared by software.
