Dmspi.rst3 Multi-bit SPI Bus
6 The MSPI (multi-bit SPI) is provided as a generic API to accommodate
8 address and data phases, and multiple signal lines during these phases.
16 .. _mspi-controller-api:
18 MSPI Controller API
21 Zephyr's MSPI controller API may be used when a multi-bit SPI controller
22 is present. E.g. Ambiq MSPI, QSPI, OSPI, Flexspi, etc.
25 not limited to high-speed, high density flash/psram memory devices, displays
28 The MSPI interface contains controller drivers that are SoC platform specific
29 and implement the MSPI APIs, and device drivers that reference these APIs.
