Software write

This field has special behavior when written by software (e.g., through csrrw).

When software tries to write csr_value, the field will be written with the return value of the function below.

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];

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