7.6.6
A data TLB protection violation exception occurs when, even though a UTLB entry contains
address translation information matching the virtual address to which a data access is made, the
actual access type is not permitted by the access right specified by the PR or EPR bit. The data
TLB protection violation exception processing carried out by hardware and software is shown
below.
(1)
In the event of a data TLB protection violation exception, hardware carries out the following
processing:
1. Sets the VPN of the virtual address at which the exception occurred in PTEH.
2. Sets the virtual address at which the exception occurred in TEA.
3. Sets exception code H'0A0 in the case of a read, or H'0C0 in the case of a write in EXPEVT
4. Sets the PC value indicating the address of the instruction at which the exception occurred in
5. Sets the SR contents at the time of the exception in SSR. The R15 contents at this time are
6. Sets the MD bit in SR to 1, and switches to privileged mode.
7. Sets the BL bit in SR to 1, and masks subsequent exception requests.
8. Sets the RB bit in SR to 1.
9. Branches to the address obtained by adding offset H'0000 0100 to the contents of VBR, and

Resolve the data TLB protection violation, execute the exception handling return instruction
(RTE), terminate the exception handling routine, and return control to the normal flow. The RTE
instruction should be issued at least one instruction after the LDTLB instruction.
