RESET:
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.
HMIE enables interrupt requests generated by the HALTA status flag or the MODF
status flag in SPSR.
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.
0 = HALTA and MODF interrupts disabled.
1 = HALTA and MODF interrupts enabled.
0 = QSPI operates normally.
1 = QSPI is halted for subsequent restart.
