Extended Error Codes The Message Instructions used to send data to the 7264 module have an error register that can be used to obtain diagnostic information from the module. This register’s address is user_tag.exerr. The following table shows the values that will be displayed in this register if the data sent to the 7264 module is not valid.• These error codes are only valid when register address user_tag.err is equal to 9. • The Message Instructions Error bit and the Extended Error Code can only be cleared by sending valid data to the 7264 module.

The message instructions described in chapter 4 above are used to send the setup data to the four channels of the 7264 module. This data consists of nine 32 bit words (36 bytes) shown in the following table. Each channel can be programmed with different setup data.All of the data must be present and valid when the message instruction is used to send the data to the 7264 module. If the data is not valid, all of the data will be ignored, the message instruction’s error bit will be set, and the extended error code will indicate exactly how the data is invalid. See chapter 3 for definitions of the set up parameters.
