14.2.3 Clock Configuration

The Kinetis Flashloader uses the clock configuration of the chip out of reset.

This section explains the general protocol for the packet transfers between the host and

the Kinetis Flashloader. The description includes the transfer of packets for different

transactions, such as commands with no data phase and commands with incoming or

outgoing data phase. The next section describes various packet types used in a

transaction.

Each command sent from the host is replied to with a response command.

Commands may include an optional data phase:

• If the data phase is incoming (from host to flashloader ), then the data phase is part

of the original command.

• If the data phase is outgoing (from flashloader to host), then the data phase is part of

the response command.

In all protocols (described in the next subsections), the Ack sent

in response to a Command or Data packet can arrive at any time

before, during, or after the Command/Data packet has

The protocol for a command with no data phase contains:

• Command packet (from host)

• Generic response command packet (to host)
