Software write
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:
OF = csr_value.OF
MINH = csr_value.MINH
SINH = csr_value.SINH
UINH = csr_value.UINH
VSINH = csr_value.VSINH
VUINH = csr_value.VUINH
EVENT = if (ary_includes?<$array_size(HPM_EVENTS), 58>(HPM_EVENTS, csr_value.EVENT)) {
return csr_value.EVENT;
} else {
return UNDEFINED_LEGAL_DETERMINISTIC;
}
