configured in order to send an acknowledge frame. The ST10F276E will not send this

Message Object but the host can request it by sending a remote frame.

The acknowledge frame is the following for the ST10F276E:

–

Standard identifier = E6h

–

DLC = 3h

–

Data0 = D5h, that is, generic acknowledge of the ST10 devices

–

Data1 = IDCHIP least significant byte

–

Data2 = IDCHIP most significant byte

For the ST10F276E, IDCHIP = 114Xh.

Note:

Two behaviors can be distinguished in ST10 acknowledging to the host. If the host is

behaving according to the CAN protocol, as at the beginning the ST10 CAN is not

configured, the host is alone on the CAN network and does not receive an acknowledge. It

automatically resends the zero frame. As soon as the ST10 CAN is configured, it

acknowledges the zero frame. The “acknowledge frame” with identifier 0xE6 is configured,

but the Transmit Request is not set. The host can request this frame to be sent and therefore

obtains the IDCHIP by sending a remote frame.

Hint: As the IDCHIP is sent in the acknowledge frame, Flash programming software now

can immediately identify the exact type of device to be programmed.
