Serial Peripheral data transfer flag
Clear by hardware to indicate data transfer is in progress or has been
approved by a clearing sequence.
Set by hardware to indicate that the data transfer has been completed.
Write Collision flag
Cleared by hardware to indicate that no collision has occurred or has
been approved by a clearing sequence.
Set by hardware to indicate that a collision has been detected.
Synchronous Serial Slave Error flag
Set by hardware when SS is modified before the end of a received data.
Cleared by disabling the SPI (clearing SPEN bit in SPCON).
Mode Fault
Cleared by hardware to indicate that the SS pin is at appropriate logic
level, or has been approved by a clearing sequence.
Set by hardware to indicate that the SS pin is at inappropriate logic level
Reserved
The value read from this bit is indeterminate. Do not change these bits.
