I want to configure the GPIF II interface of CYUSB3014 in 32-bit parallel bus + Slave FIFO mode (bidirectional).
This clock frequency is stated in the data sheet as a maximum of 100MHz, but is it variable if it is 100MHz or less?
I want to change to 50MHz / 66MHz / 80MHz.
Also, if I change the clock frequency, do I need to change the FW? If it is yes, where and how should I change it?
Thanks,
Tetsuo

Hello Tetsuo,
In the synchronous slave modes, the supported interface clock range is from 10 MHz to 100 MHz.
For reference, you can refer to this KBA

Biren-san,
Thank you for your comment.
I read the KBA you showed.
In my understanding, in Slave mode, the user does not need to set anything in GPIF or FW. Is it correct?
Thanks,
Tetsuo
