[Gems-users] Usage of format field in .sm files

[Hemayet Hossain <hossain@xxxxxxxxxxxxxxxx>]

Hi Everybody,
I have a quick question. In MSI_MOSI_CMP_* protocol I found one filed 
format having value "!r", "!b" like in the following examples.
States....
M, desc="Modified", format="!b";
.
.
events....
Proc_last_int_ack, "Proc last on-chip L1 Cache ack", desc="Last on-chip 
L1 Cache ack", format="!r";
Can anybody tell me what is the use of format in those cases?
Thanks.
