Serial Peripheral Interface (SPI)
8.6.2 Serial Peripheral Status Register
Technical Data
176
Address: $0029
SPIF — SPI Transfer Complete Flag
WCOL — Write Collision Bit
MODF — Mode Fault Bit
Reset:
Read:
Write:
SPIF is set upon completion of data transfer between the processor
and the external device. If SPIF goes high, and if SPIE is set, a serial
peripheral interrupt is generated. To clear the SPIF bit, read the SPSR
with SPIF set, then access the SPDR. Unless SPSR is read (with
SPIF set) first, attempts to write SPDR are inhibited.
Clearing the WCOL bit is accomplished by reading the SPSR (with
WCOL set) followed by an access of SPDR.
To clear the MODF bit, read the SPSR (with MODF set), then write to
the SPCR.
