Supervisor_Statistics_Transfer_Status
Description: Indicates the status of a statistics block transfer.
Table 342. Supervisor_Statistics_Transfer_Status Register Parameters
Table 343. Supervisor_Statistics_Transfer_Status Field Parameters
This register provides basic status for statistics block transfers. A statistics block transfer is initiated by writing the
block’s transfer destination address to Supervisor_Statistics_Transfer_Addr. Upon initiation of the trans-
fer, statistics_transfer_busy is automatically asserted and remains asserted throughout the duration of the
transfer. At the completion of the transfer, statistics_transfer_busy is deasserted and
statistics_transfer_done is asserted. statistics_transfer_done is also made available to the super-
visor as an interrupt-generating indication. The supervisor must write a one to the bit position of
statistics_transfer_done in order to deassert the bit and cancel its indication.

This bit is asserted upon the completion of a statis-
tics block transfer. It is reset by writing a one to its
bit position.
This bit is asserted during the transfer of the statis-
tics block to indicate that such a transfer is in pro-
cess.
