MCP Serial Transport Protocol

RESYNCHRONIZATION
Resynchronization of the protocol may be attempted at three consecutive levels. If one level is
unsuccessful, then the next level is tried:
• For the host:
1. retransmission of frames
2. use of S(RESYNC request)
3. device reset or deactivation
• For the device:
1. retransmission of frames
2. use of S(RESYNC request)
3. without any action from the host, the device becomes idle
