To ensure proper operation, set the QSPI enable bit (SPE) in SPCR1 only after initializing the other control
registers. Setting this bit starts the QSPI.
Rewriting the same value to a control register does not affect QSPI operation with the exception of writing
NEWQP in SPCR2. Rewriting the same value to these bits causes the RAM queue pointer to restart
execution at the designated location.
Before changing control bits, the QSPI should be halted. Writing a different value into a control register
other than SPCR2 while the QSPI is enabled may disrupt operation. SPCR2 is buffered, preventing any
disruption of the current serial transfer. After the current serial transfer is completed, the new SPCR2 value
becomes effective.
15.6.1.1
SPCR0 contains parameters for configuring the QSPI before it is enabled. The CPU has read/write access
to SPCR0, but the QSPI has read access only. SPCR0 must be initialized before QSPI operation begins.
Writing a new value to SPCR0 while the QSPI is enableddisrupts operation.

Access
S = Supervisor access only
S/U = Supervisor access only or unrestricted user access (assignable data space).
Eight-bit registers, such as SPCR3 and SPSR, are on 8-bit boundaries. 16-bit registers such as SPCR0 are on 16-bit
boundaries.
