This CSR may store a value that is different from what software attempts to write.

When a software write occurs (e.g., through csrrw), the following determines the written value:

COUNT = CSR[mcycle].COUNT = {csr_value.COUNT[31:0], CSR[minstret].COUNT[31:0]};
return csr_value.COUNT;

This CSR may return a value that is different from what is stored in hardware.

return CSR[minstret].COUNT[63:32];
