XBEE SC2 802.15.4 coordinator multiple TX

XBEE SC2 coordinator.
I can send multiple frames (TX64 request 41bytes) without waiting for the ACK (TXstatus) after each TX64 only checking for the CTS.
The module can transmit another frame while previous frame retries are in progress.

I am not sure if there is a question there. Can you rephrase your question?

I’m sorry for my bad english

My question is:
After sending from my host micro a TX64 (0x00) frame for endpoint1, I must wait the TXstatus(0x89) or I can send another TX64 (0x00) frame for endpoint2 without waiting previous tx frame reply ?
