I was reviewing the silicon errata for Rev2 of the Nrf52840 and I found this.
[204] RADIO: Switching between TX and RX causes unwanted emissions
This anomaly applies to IC Rev. Revision 2, build codes CKAA-Dx0, QIAA-Dx0.
It was inherited from the previous IC revision Engineering D.
Symptoms
Unwanted emissions are experienced when switching from TX to RX.
Conditions
Switching from TX to RX without using DISABLE.
Consequences
Unwanted emissions occur on the channel used for RX.
Workaround
Always use DISABLE when switching from TX to RX.
Question
Is the S140 v6.1.1 SD impacted by this and does it fix this issue?
Thanks.
