16.4.8. ebfm_cfgrd_nowt Procedure
The ebfm_cfgrd_nowt procedure reads up to four bytes of data from the specified configuration register and stores the data in the BFM shared memory. This procedure returns as soon as the VC interface module has accepted the transaction, allowing other reads to be issued in the interim. Use this procedure only when successful completion status is expected and a subsequent read or write with a wait can be used to guarantee the completion of this operation.
