C05E      OTA Handler

xxxF      User HW Profiles

FFFF      Reserved

HW profile ID (HWPID from now) uniquely specifies (the functionality of) the device, the user peripherals it implements, its behavior, etc. The only device having the same HWPID as the DPA Request will execute the request. When 0xFFFF is specified then the device with any HW profile ID will execute the request. Note - HWPID numbers used throughout this document are fictitious ones.

PData

[0-56B]

An array of bytes. The maximum length is limited to 56 bytes (decimal).

Optional message data.
