The ATS12NSOUR characteristics are:
Performs stage 1 and 2 address translations as defined for PL0 and the Non-secure state, with permissions as if reading from the given virtual address.
ATS12NSOUR is a 32-bit System instruction.
The ATS12NSOUR input value bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
Input address for translation |
Input address for translation. The resulting address can be read from the PAR.
This instruction takes a VA as input. The resulting address is the PA that is the output address of the stage 2 translation.
Accesses to this instruction use the following encodings:
opc1 | opc2 | CRn | coproc | CRm |
---|---|---|---|---|
0b000 | 0b110 | 0b0111 | 0b1111 | 0b1000 |
