Functional overview

STM32L412xx

48/192

DS12469 Rev 8

The Quad SPI interface supports:

•

Three functional modes: indirect, status-polling, and memory-mapped

•

Dual-flash mode, where 8 bits can be sent/received simultaneously by accessing two

flash memories in parallel.

•

SDR and DDR support

•

Fully programmable opcode for both indirect and memory mapped mode

•

Fully programmable frame format for both indirect and memory mapped mode

•

Each of the five following phases can be configured independently (enable, length,

single/dual/quad communication)

–

Instruction phase

–

Address phase

–

Alternate bytes phase

–

Dummy cycles phase

–

Data phase

•

Integrated FIFO for reception and transmission

•

8, 16, and 32-bit data accesses are allowed

•

DMA channel for indirect mode operations

•

Programmable masking for external flash flag management

•

Timeout management

•

Interrupt generation on FIFO threshold, timeout, status match, operation complete, and

access error
