Description
SPI Interrupt Flag
Set by hardware when an 8-bit shift is completed.
Cleared by hardware when reading or writing SPDAT after reading SPSTA.
Write Collision Flag
Set by hardware to indicate that a collision has been detected.
Cleared by hardware to indicate that no collision has been detected.
Reserved
The value read from this bit is indeterminate. Do not set this bit.
Mode Fault
Set by hardware to indicate that the SS pin is at an appropriate level.
Cleared by hardware to indicate that the SS pin is at an inappropriate level.
Reserved
The value read from these bits is indeterminate. Do not set these bits.
