Bit7
This bit is set to logic 1 by hardware at the end of a data transfer. If interrupts are enabled,
setting this bit causes the CPU to vector to the SPI0 interrupt service routine. This bit is
not automatically cleared by hardware. It must be cleared by software.
WCOL: Write Collision Flag.
This bit is set to logic 1 by hardware (and generates a SPI interrupt) to indicate a write to
the SPI data register was attempted while a data transfer was in progress. It is cleared by
software.
This bit is set to logic 1 by hardware (and generates a SPI interrupt) when a master mode
collision is detected (NSS is low and MSTEN = 1). This bit is not automatically cleared by
hardware. It must be cleared by software.
This bit is set to logic 1 by hardware (and generates a SPI interrupt) when the receive
buffer still holds unread data from a previous transfer and the last bit of the current transfer
is shifted into the SPI shift register. This bit is not automatically cleared by hardware. It
must be cleared by software.
This bit is set to logic 1 by hardware while a master mode transfer is in progress. It is
cleared by hardware at the end of the transfer.
This bit is set to logic 1 whenever the NSS pin is low indicating it is enabled as a slave. It
is cleared to logic 0 when NSS is high (slave disabled).
0: Disable master mode. Operate in slave mode.
1: Enable master mode. Operate as a master.
This bit enables/disables the SPI.
0: SPI disabled.
1: SPI enabled.
SPIF: SPI Interrupt Flag.
MODF: Mode Fault Flag.
RXOVRN: Receive Overrun Flag.
TXBSY: Transmit Busy Flag.
SLVSEL: Slave Selected Flag.
MSTEN: Master Mode Enable.
SPIEN: SPI Enable.
