System ControlUsage constraints The HCPTR is:• A read/write register.• Only accessible from Hyp mode or from Monitor mode whenSCR.NS is 1.• If a bit in the NSACR prohibits a Non-secure access, then thecorresponding bit in the HCPTR behaves as RAO/WI forNon-secure accesses. See the bit descriptions for more information.ConfigurationsAvailable in all configurations.Attributes See the register summary in Table 4-3 on page 4-5.Figure 4-30 shows the HCPTR bit assignments.31 30 16 15 14 12 11 10 90ReservedReservedTCPACTCP10TCP11ReservedTASEFigure 4-30 HCPTR bit assignmentsARM DDI 0438I Copyright © 2011-2013 ARM.
