Host Requirements
The reader must send a CMD_ACK within the programmable Serial Response
Timeout to acknowledge receipt of all messages, unless noted otherwise in the
message description section. If the host sends data and does not receive a response
within the programmable serial response timeout, it resends the message (with the
retransmit status bit set) before declaring a failure. The host should limit the number
of retries.
Reader Requirements
The host must send a CMD_ACK within the programmable Serial Response Timeout
to acknowledge receipt of all messages, unless noted otherwise in the message
description section. If the reader does not receive an ACK within this time period, it
sends the previous message again. The reader retries twice more (with the
retransmit status bit set) before declaring a transmit error.
