Hi community,
I have a question about i.MX6 eCSPI.
I understand that CHANEL_SELECT field in ECSPIxCONREG register is set when i.MX6 is master mode and communicates with a external slave device.
Then, I want to confirm whether CHANNEL_SELECT field is also set in i.MX6DQ is eCSPI slave mode or not.
Would you let me know it?

Hello,
The CHANNEL_SELECT field cannot be used to get the SS status.

Hello,
According to section 21.4.2 (Slave Mode) of the i.MX6 D/Q RM :
"In this configuration, Chip Select (SS) becomes an input signal, and is used to control
data transfers through the Shift register, as well as to load/store the data FIFO."
Have a great day,
Yuri

Dear Yuri,
Did you mean "we can confirm whether SS is input to i.MX6 or not by reading CHANNEL_MODE field"?
Or in slave mode, SS status is not affected to CHANNEL_MODE?
