RESET:
SPCR2 contains QSPI queue pointers, wraparound mode control bits, and an interrupt
enable bit. SPCR2 is buffered. New SPCR2 values become effective only after com-
pletion of the current serial transfer. Rewriting NEWQP in SPCR2 causes execution to
restart at the designated location. Reads of SPCR2 return the value of the register, not
the buffer.
This field contains the last QSPI queue address.
This field contains the first QSPI queue address.
SPCR3 contains the loop mode enable bit, halt and mode fault interrupt enable, and
the halt control bit. SPCR3 must be initialized before QSPI operation begins. Writing
a new value to SPCR3 while the QSPI is enabled disrupts operation. SPSR contains
information concerning the current serial transmission.
LOOPQ controls feedback on the data serializer for testing.
0 = QSPI interrupts disabled.
1 = QSPI interrupts enabled.
0 = Wraparound mode disabled.
1 = Wraparound mode enabled.
0 = Wrap to pointer address $0.
1 = Wrap to address in NEWQP.
0 = Feedback path disabled.
1 = Feedback path enabled.
