The timing of WOR_EVENT1 on CC1121

Other Parts Discussed in Thread: CC1121

Hello,

In case that GPIO is set to WOR_EVENT1, when GPIO is set?
I think the timing is Event 1 timeout; therefore GPIO is set at the end of tEvent1.
After GPIO is set, MCU detects the signal and sends SRX strobe to CC1121.

Best Regards.

Hi Nomoto

Please see Figure 1 on page 4 in the CC112x/CC120x RX Sniff Mode Application Report (http://www.ti.com/lit/SWRA428).

Hello Siri-san,

Thank you for your reply.
However, I can't understand when GPIO is set from Figure 1; because, the figure doesn't show the GPIO signal.
Let me know when GPIO (which is set to WOR_EVENT1) is set.

Best Regards.

Hi Nomoto-san

I am not sure what you mean. The timeline shows a mark when Event 0 occur and Event 1 occur. This is when the EVENT0 and EVENT1 signals are asserted and de-asserted when output on a GPIO.
