This anomaly applies to IC Rev. Engineering D, build codes CLAA-DA0, QKAA-DB0.
Application
Reader may not accept the response from the tag.
The time between SLP_REQ and ALL_REQ sent by the Reader is shorter than the time configured in FRAMEDELAYMAX.
The protocol timing is violated, and a Reader may not accept the response from the tag.
Ensure that FRAMEDELAYMAX is set to the default value when the NFCT is in states IDLE or SLEEP_A. The workaround is included in nrfx v2.0.0 and later.
