Programmable Registers
19.4.49 AHB Layer 3 Performance Metric for Valid Bus Cycles Register
Used for AHB bus utilization measurements, the AHB Performance Metric for Valid Bus
Cycles Register counts the number of actual AHB cycles in which a data transfer is
completed.
This field counts the number of AHB cycles in which a master completed a data transfer (a
data-phase in which HREADY is high).
EXAMPLE
Address:
Re-
19.4.50 Default First Level Page Table Movable PTE Locator 0
This register is used by the DFLPT to set the location for MPTE0.
When using the hardware-based Default First-Level Page Table (DFLPT), program this
value to set the location for Movable PTE (MPTE0) to any of the 4096 sections.
