4.3.22.  CtGxiRd

The MBX GXI performs a read transfer completely disjoint from the address cycle. Transfer requests are acknowledged in the address cycle with the GAREADY signal, and transfers are completed in subsequent cycles, which are acknowledged by the GDREADY signal. The MBX initiates a read transfer request by driving GWRITE LOW and GTRANS HIGH.

This register contains the total count of completed read transfers that have occurred on the MBX GXI Bus. This register does not contain the total number of accepted transfer requests. The count is disabled by default and can be controlled through the AHBMONCtrlReg, and reset through the AHBMONRstCtrs.
