NOT USED
RESET:
When STOP is set, the QSM enters low-power stop mode. The system clock input to
the module is disabled. While STOP is set, only QSMCR reads and writes are guar-
anteed to be valid, but only writes to the QSPI RAM and other QSM registers are guar-
anteed valid. The SCI receiver and transmitter and the QSPI should be disabled
before STOP is set. To stop the QSPI, set the HALT bit in SPCR3, wait until the HAL-
TA flag is set, then set STOP. To stop the SCI, clear the TS and RE bits in SCCR1.
FRZ1 determines what action is taken by the QSPI when the IMB FREEZE signal is
asserted.
This bit has no effect because the CPU16 in the MCU operates only in supervisor
mode.
The IARB field is used to arbitrate between simultaneous interrupt requests of the
same priority. Each module that can generate interrupt requests must be assigned a
unique, non-zero IARB field value in order to request an interrupt.
Used for factory test only.
The values of ILQSPI[2:0] and ILSCI[2:0] in QILR determine the priority of QSPI and
SCI interrupt requests. QIVR determines the value of the interrupt vector number the
QSM supplies when it responds to an interrupt acknowledge cycle.
0 = QSM clock operates normally.
1 = QSM clock is stopped.
0 = Ignore the IMB FREEZE signal.
1 = Halt the QSPI on a transfer boundary.
