5.5.1 QSPI Pins
Seven pins are associated with the QSPI. When not needed for a QSPI function, they can be configured
as general-purpose I/O pins. The PCS0/SS pin can function as a peripheral chip-select output, slave
select input, or general-purpose I/O. Refer to Table 54 for QSPI input and output pins and their func-
tions.
5.5.2 QSPI Registers
The programming model for the QSPI submodule consists of the QSM global and pin control registers,
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 de-
fined state and can then be changed by the CPU. Reset values are shown below each register.
Table 55 shows a memory map of the QSPI.
Writing a different value into any control register except SPCR2 while the QSPI is enabled disrupts op-
eration. 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 designated lo-
cation.
