htimedeltah
Hypervisor time delta, upper half
Upper half of the htimedelta CSR.
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:
DELTA = CSR[htimedelta].DELTA = {csr_value.DELTA, CSR[htimedelta].DELTA[31:0]}; return csr_value.DELTA;
