Good day. Can you help clarify if you are actually getting clock pulses of the pin?
Can you also provide the scope shot of the pulse? Thanks.
I didn't probe the SDP pin with a scope. But I was reading the "SDP1 DATA" bit periodically in "Device Control Register - CTRL" to check if there are any pulses.
Not sure if it is the right method, but I could see the level change with period read operations. But there were no interrupts to the driver.
I am not sure if I can provide a shot on scope, but I'll try.
