OctoSPI IO manager (OctoSPIIOM)

The OctoSPI IO Manager is a low level interface allowing:

•

Efficient OctoSPI pin assignment with a full IO Matrix (before alternate function map)

•

Multiplexing single/dual/quad/octal SPI interface over the same bus

The OctoSPI IO Manager has the following features:

•

Support up to two single/dual/quad/octal SPI Interface

•

Support up to eight ports for pin assignment

•

Fully programmable IO matrix for pin assignment by function (data/control/clock)

•

Muxer for Single/Dual/Quad/Octal SPI interface multiplexing over the same bus

Serial wire JTAG debug port (SWJ-DP)

The Arm® SWJ-DP interface is embedded, and is a combined JTAG and serial wire debug

port that enables either a serial wire debug or a JTAG probe to be connected to the target.

Debug is performed using two pins only instead of five required by the JTAG (JTAG pins

could be re-used as GPIO with alternate function): the JTAG TMS and TCK pins are shared

with SWDIO and SWCLK, respectively, and a specific sequence on the TMS pin is used to

switch between JTAG-DP and SW-DP.
