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. The CPU32 has read/write access to SPCR3, but the QSM has
read access only. SPCR3 must be initialized before QSPI operation begins. Writing a
new value to SPCR3 while the QSPI is enabled disrupts operation.
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.
When HALT is set, the QSPI stops on a queue boundary. It remains in a defined state
from which it can later be restarted.
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.
