For the whole sentence, *"when NumTx reaches MAX_NUMTX, both NumTx and NumTxAck MUST be divided by 2* *For example, when MAX_NUMTX is set to 256, from NumTx=255 and NumTxAck=127, the counters become NumTx=128 and NumTxAck=64 if one frame is sent to the parent with an Acknowledgment received."* In this case, MAX_NUMTX should be set to 256. Even NumTx is recommended to use 1 byte later, when comparing NumTx and MAX_NUMTX, a casting can be applied and doesn't break 1 byte storage of NumTx.
