Table 17. Expanded Controller ID Report
Controller Type – The identifier M1 is used. M identifies it as an EX based USB
controller. The 1 identifies it as the first model of this type. This value is treated as an
integer, not two characters. This means that the 1 will be transmitted first.
Note: If you received an identifier of M0, you must issue a Reset with a wValue of 5.
This must be done twice to lock in the values.
FW Major Revision – This can range from 0 to 99. This is a BCD value, i.e., major
revision 23 is sent as 0x23.
FW Minor Revision – This can range from 0 to 99. This is a BCD value, i.e., minor
revision 23 is sent as 0x23.
Features – This identifies the special features of the controller. This is a bitmapped field.
Constants Checksum – 2-byte checksum for the constants data section.
Max Parameter Write -- The largest transfer that can take place. This only affects the
Read Parameter requests.
Code Checksum – 4-byte checksum for the program section of the code.
ASIC Type – this indicates the type and version of the ASIC in the controller. The value
0x0100 indicates the first EX revision. The high byte is used to note major ASIC
changes, such as a new ASIC family, and the low byte indicates changes within a family.
