Serial Peripheral Status Register
(SPSTA)
The Serial Peripheral Status Register contains flags to signal the following conditions:
Data transfer complete
Write collision
Inconsistent logic level on SS pin (mode fault error)
Table 80 describes the SPSTA register and explains the use of every bit in the register.

Mnemonic Description
7SPIF
Serial Peripheral Data Transfer Flag
Cleared 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.
6WCOL
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.
5
SSERR
Synchronous Serial Slave Error Flag
Set by hardware when SS is deasserted before the end of a received data.
Cleared by disabling the SPI (clearing SPEN bit in SPCON).
4MODF
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.
