7.4.2 QSPI Registers
The programmer's model for the QSPI submodule consists of the QSM global and pin control reg-
isters, four QSPI control registers, one status register, and the 80-byte QSPI RAM.
The CPU can read and write to registers and RAM. The four control registers must be initialized
before the QSPI is enabled to ensure defined operation. SPCR1 should be written last because it
contains QSPI enable bit SPE. Asserting this bit starts the QSPI. The QSPI control registers are
reset to a defined state and can then be changed by the CPU. Reset values are shown below each
register.
Table 58
shows a memory map of the QSPI.
Writing a different value into any control register except SPCR2 while the QSPI is enabled disrupts
operation. SPCR2 is buffered to prevent disruption of the current serial transfer. After completion of
the current serial transfer, the new SPCR2 values become effective.
Writing the same value into any control register except SPCR2 while the QSPI is enabled has no
effect on QSPI operation. Rewriting NEWQP[3:0] in SPCR2 causes execution to restart at the des-
ignated location.
