8.10.9 Quad Serial Peripheral Interface (QSPI)

The quad serial peripheral interface (QSPI) module is a kind 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. The QSPI works as a master only. The QSPI in the device is primarily intended for fast booting from quad-SPI flash memories.

The QSPI supports the following features:

  • Programmable clock divider
  • Six-pin interface
  • Programmable length (from 1 to 128 bits) of the words transferred
  • Programmable number (from 1 to 4096) of the words transferred
  • Support for 3-, 4-, or 6-pin SPI interface
  • Optional interrupt generation on word or frame (number of words) completion
  • Programmable delay between chip select activation and output data from 0 to 3 QSPI clock cycles

Section 8.10.9.2 and Section 8.10.9.3 assume the operating conditions stated in Section 8.10.9.1.
