CAEN TDC v1190 Firmware Update Rev0.7
=====================================

If you have our VME bridges (V1718 or V2718), you can upgrade the board 
just executing the script "V1190Upgrade.vbs" for each TDC in setup; 
it asks for the Base Address of the board and then writes the flash memory 
with the RBF file contained in the directory.

If you have a different VME master, you must recompile the program CVUpgrade.c 
providing the VME functions (essentially the single data read/write 
access) where indicated in the source code.

In the new firmware, the 11th bit (Bit Mask = 0x0800) of the Control 
Register (Address Offset = 0x1000) allows to see the 5 MSB of the 
Extended Trigger Time Tag in the 5 MSB of the Global Trailer (normally 
these bit contain the GEO address, but this is redundant since it is 
already reported in the Global Header). Therefore, the complete 
Trigger Time Tag (with 25ns resolution) will be the following:

Time Tag (32 bit @ 25ns) = (Ext_Trg_Time_Tag_Word & 0x07FFFFFF) << 5 
+ (Global_Trailer_Word & 0x1F)

The BunchID from the HPTDC is unchanged but now you can ignore it. 
The Time Tag rolls every 108s as before.
