I use I2C I/F of CY8C22645. I have to reply quickly to device using "ACK" and understand that it need interrupt to reply with "ACK" regarding "I2CHW_1Int.asm".
I want to reply more quickly with "ACK" without software processing(include Interrupt). It is better that auto reply with only Hardware.
Do you have any solution about that?
Unfortunately, there is no means to "auto" ack direct from hardware. The quickest you can achieve is by acknowledging as quickly as possible in the I2C ISR.
