Hi,

   I see the RM of RT1060, as if the LPSPI module can support QSPI device, but it is very simply described in RM, and there is no example for the usage in SDK, the LPSPI module can support QSPI device? Thanks.

Best Regards,

Fred Fu

Hi

The LPSPI can be used in Quad data mode by configuring the WIDTH field of the transmit command register for 4-bit transfer (which can be done on a per-transaction basis).
The LPSPI pins use their data functions in this case

QSPI flash devices can usually operate in single-bit mode so the LPSPI can also operate in standard 1 bit mode with them too if the data rate is not critical.
