05h (Last TX Confirm)

This object stores information about last confirm message received (among

PHY_DataConfirm Section 3.3.13, DL_DataConfirm Section 3.3.16, SS_DataConfirm

Section 3.3.20).

Its field values are equal to those notified by last confirm message and presented in the first

five bytes (0

 2) of the ConfirmData (Table 37). It can be read only.
