TDA4VM: Format of 1722 message

Part Number: TDA4VM

Dear Sir,

Would you please provide the format of 1722 message in gateway-demos/pctools/send_1722.c  => which spec ?

<1> NTSCF PDU Format

<2> ACF message Format

For example in send_1722.c

    /*Now prepare the ACF message payload*/
    temp_byte = 0;
    temp_byte |= (((uint8_t)ACF_MSG_TYPE_CAN & 0x7f) << 1);
    temp_byte |= (uint8_t)(((uint16_t)DEFAULT_ACF_MSG_LENGTH_CAN & 0x100) >> 8);
    *(frame + curr_byte_offset++) = temp_byte;

    /* Next byte is all ACF message length*/
    temp_byte = DEFAULT_ACF_MSG_LENGTH_CAN & 0xff;
    *(frame + curr_byte_offset++) = temp_byte;

We would like to know the Format of  ACF message

Thansk

Best Regards

CT Yen
