I'm currently using the TC234 QSPI module in master mode, and the MTSR output is idle high.
Is there a way to change this so the output idle polarity is low?

From the QSPI hardware perspective, in master mode the MTSR output will maintain the last bit value transmitted.
Say for example you have 8-bit data in MSB mode. The data written is 0x00 the MTSR signal will maintain a "0" or low level, if you wrote data 0x01 the MTSR signal will maintain a "1' or high level.

Hi, cwunder.
In the TC399 (KIT_A2G_TC399_5V_TRB_S), I have confirmed the same behavior for the MTSR signal in QSPI master mode on the actual device.
Can I expect the same behavior for QSPI on the TC399 from a hardware standpoint as shown below?
" in master mode the MTSR output will maintain the last bit value transmitted."
Thank you!
Best Regards.
