Unable to use iMX RT1052 FLEXIO in parallel transmit mode ( with MCUXpresso SDK 2.3.0.)

Question asked by James Zhang on May 7, 2018

I want to use IMX RT1052 FLEXIO in parallel transmit mode. 

According to the iMX RT1050 Processor Reference Manual, RT1052 FLEXIO supports parallel shift mode (4, 8, 16, 32 bits), but I can not configure FLEXIO to parallel transmit mode with MCUXpresso SDK 2.3.0.

I found there is no FLEXIO feature definition (including FSL_FEATURE_FLEXIO_HAS_PARALLEL_WIDTH ) in  i.MX RT1052 chip feature definition file MIMXRT1052_features.h. 

Is the FLEXIO feature disabed in RT1052, or is it just a BUG in SDK 2.3.0?
