SPCR2 contains QSPI configuration parameters. The CPU can read and write this register; the QSM
has read access only. Writes to SPCR2 are buffered. A write to SPCR2 that changes a bit value while
the QSPI is operating is ineffective on the current serial transfer, but becomes effective on the next se-
rial transfer. Reads of SPCR2 return the current value of the register, not of the buffer.
SPIFIE enables the QSPI to generate a CPU interrupt upon assertion of the status flag SPIF.
WREN enables or disables wraparound mode.
When wraparound mode is enabled, after the end of queue has been reached, WRTO determines
which address the QSPI executes.
This field contains the last QSPI queue address.
This field contains the first QSPI queue address.
SPCR3 contains QSPI configuration parameters. The CPU can read and write SPCR3, but the QSM
has read-only access.
LOOPQ controls feedback on the data serializer for testing.
HMIE controls CPU interrupts caused by the HALTA status flag or the MODF status flag in SPSR.
