System ControlTable 4-59 HCPTR bit assignments (continued)Bits Name Function[11] TCP11 Trap coprocessor 11:0 If NSACR.CP11 is set to 1, then Hyp mode can access CP11, regardless of thevalue of CPACR.CP11.NoteThis bit value has no effect on possible use of CP11 from Non-secure PL1 and PL0modes.1 Trap valid Non-secure accesses to CP11 to Hyp mode.When TCP11 is set to 1, any otherwise-valid access to CP11 from:• A Non-secure PL1 or PL0 mode is trapped to Hyp mode.• Hyp mode generates an Undefined Instruction exception, taken in Hypmode.If VFP and NEON are not implemented, this bit is RAO/WI. See the ARM ® Architecture ReferenceManual ARMv7-A and ARMv7-R edition for more information.[10] TCP10 Trap coprocessor 10:0 If NSACR.CP10 is set to 1, then Hyp mode can access CP10, regardless of thevalue of CPACR.CP10.NoteThis bit value has no effect on possible use of CP10 from Non-secure PL1 and PL0modes.1 Trap valid Non-secure accesses to CP10 to Hyp mode.When TCP10 is set to 1, any otherwise-valid access to CP10 from:• A Non-secure PL1 or PL0 mode is trapped to Hyp mode.• Hyp mode generates an Undefined Instruction exception, taken in Hypmode.If VFP and NEON are not implemented, this bit is RAO/WI.
