QSPI

The Quad SPI (QSPI) module is a type of SPI module that allows single, dual or quad read access to external SPI devices. This module has a memory mapped register interface, which provides a direct interface for accessing data from external SPI devices and thus simplifying software requirements. It works as a master only. There is one QSPI module in the device and it is primary intended for fast booting from quad-SPI flash memories.

General SPI features:

  • Programmable clock divider
  • Six pin interface (DCLK, CS_N, DOUT, DIN, QDIN1, QDIN2)
  • 4 external chip select signals
  • Support for 3-, 4- or 6-pin SPI interface
  • Programmable CS_N to DOUT delay from 0 to 3 DCLKs
  • Programmable signal polarities
  • Programmable active clock edge
  • Software controllable interface allowing for any type of SPI transfer

NOTE

For more information, see the Quad Serial Peripheral Interface section of the Device TRM.

CAUTION

The IO Timings provided in this section are only valid for some QSPI usage modes when the corresponding Virtual IO Timings or Manual IO Timings are configured as described in the tables found in this section.

CAUTION

The IO Timings provided in this section are only valid when all QSPI Chip Selects used in a system are configured to use the same Clock Mode (either Clock Mode 0 or Clock Mode3).

Table 5-71 and Table 5-72 present timing and switching characteristics for Quad SPI interface.

  1. The Y parameter is defined as follows:
    If DCLK_DIV is 0 or ODD then, Y equals 0.5.
    If DCLK_DIV is EVEN then, Y equals (DCLK_DIV/2) / (DCLK_DIV+1).
    For best performance, it is recommended to use a DCLK_DIV of 0 or ODD to minimize the duty cycle distortion. The HSDIVIDER on CLKOUTX2_H13 output of DPLL_PER can be used to achieve the desired clock divider ratio. All required details about clock division factor DCLK_DIV can be found in the Device TRM.
  2. P = SCLK period.
  3. M = QSPI_SPI_DC_REG.DDx + 1 when Clock Mode 0.
    M = QSPI_SPI_DC_REG.DDx when Clock Mode 3.
    N = 2 when Clock Mode 0.
    N = 3 when Clock Mode 3.

  1. P = SCLK period.
  2. Clock Modes 1 and 2 are not supported.
  3. The Device captures data on the falling clock edge in Clock Mode 0 and 3, as opposed to the traditional rising clock edge. Although non-standard, the falling-edge-based setup and hold time timings have been designed to be compatible with standard SPI devices that launch data on the falling edge in Clock Modes 0 and 3.

NOTE

To configure the desired Manual IO Timing Mode the user must follow the steps described in section Manual IO Timing Modes of the Device TRM.

The associated registers to configure are listed in the CFG REGISTER column. For more information see the Control Module chapter in the Device TRM.

Manual IO Timings Modes must be used to guarantee some IO timings for QSPI. See Table 5-32, Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 5-73, Manual Functions Mapping for QSPI for a definition of the Manual modes.

Table 5-73 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.
