30.2 Introduction
Figure 30-1 is a block diagram of the Quad Serial Peripheral Interface (QuadSPI) module.
SFM Command Applicable in SFM mode only: A SFM command consists of an instruction code and all other
parameters (e.g. size or mode bytes) needed for that specific instruction code. Triggering a
command either initiates a transaction on the external serial flash or results in an error. Refer
to
Table 30-50 for details.
SFM mode The QuadSPI is set up to for an external serial flash device.
SPI Command Applicable in SPI Master mode only. A SPI Command is part of each TX FIFO entry
specifying the parameters for the transmission of that specific entry.
SPI Master mode The QuadSPI is set up as SPI master to communicate with external SPI slave devices.
SPI modes SPI Slave mode or SPI Master mode.
SPI Slave mode The QuadSPI is set up as SPI slave to communicate with an external SPI master device.
Transaction A transaction consists of all flags, data and signals in either direction to execute a command
for an attached serial flash device. It is a combination of chip select, sclk, instruction code,
address, mode- and/or dummy bytes, transmit and/or receive data.
Transfer Format The combination of SCK polarity, SCK phase, data MSB/LSB first, and associated CS signal
timing during a serial transmission
TX FIFO First-In-First-Out buffer for transmit data
