Table 47. DESCRIPTION OF THE MAC_Frame FIELD
7.4.3 MA_DATA_Confirm
external controller (SLAVE or MASTER) either as positive
acknowledgment when a MA_DATA_Request has
successfully been transmitted by the physical layer, or as
negative acknowledgment when the transmission has been
refused. The positive acknowledgment is sent after the
Table 48. TRANSMISSION STATUS
Frame Format:
7.4.4 MA_DATA_Indication_Bad_CRC
deliver an erroneous frame. This command is only used if the Bad CRC transmitting option is chosen during the configuration.
The frame with errors can be used by the external controller to analyze the faults.
Frame Format:
7.4.5 SPY_No_SubFrame

of the repetition (if the credit is higher than zero). The
Transmission_Status byte contains a value corresponding at
this positive or negative acknowledgment. The different
