Can be up to 20 bytes of requested read data.
The FlashReadResourceResponse packet is sent by the target in response to the host
sending a FlashReadResource command. The FlashReadResourceResponse packet
contains the framing packet data and command packet data, with the command/response
tag set to a FlashReadResourceResponse tag value (0xB0), and the flags field set to
kCommandFlag_HasDataPhase (1).

• For a list of commands supported by the Flashloader, see Table 13-2, Commands
supported.
• For a list of status codes returned by the Kinetis Flashloader, see Table 13-47,

NOTE
All the examples in this section depict byte traffic on serial
peripherals that use framing packets. USB HID transactions use
the USB HID report packets instead of the serial framing
packets shown in this section. Please refer to the HID reports
section for details of the USB HID packet structure.
