• Software (Initial Page Write Handler) Operations
4.5.5
If a CPU address error or MMU exception occurs in a specific instruction in the repeat loop, the
SPC may indicate an illegal address or the repeat loop cannot be reexecuted correctly even if the
SPC is correct. Accordingly, if a CPU address error or MMU exception occurs in a specific
instruction in the repeat loop, this LSI generates a specific exception code to set the EXPEVT to
H
address error and to H'0D0 for a TLB protection violation exception. In addition, a vector offset
for TLB miss exception is H'100. For details, refer to section 7.4.3, Exception in Repeat Control
Period.

The software must execute the following operations:
A. Retrieve the required page table entry from external memory.
B. Set the D bit of the page table entry in the external memory to 1.
C. Write the value of the PPN field and the PR, SZ, C, D, SH, and V bits of the page table
D. If using software for way selection for entry replacement, write the desired value to the RC
E. Issue the LDTLB instruction to load the contents of PTEH and PTEL into the TLB.
F. Issue the RTE instruction to terminate the handler and return to the instruction stream. The
