 Read access to bit _X_ is subject to the same mcounteren (or mcounteren and
 hcounteren) CSRs that mediate access to the hpmcounter CSRs by S-mode (or
-VS-mode). In M and S modes, scountovf bit _X_ is readable when mcounteren bit
+VS-mode). In M-mode, scountovf bit _X_ is always readable. In S/HS-mode, scountovf bit _X_ is readable when mcounteren bit
 _X_ is set, and otherwise reads as zero. Similarly, in VS mode, scountovf bit
 _X_ is readable when mcounteren bit _X_ and hcounteren bit _X_ are both set,
 and otherwise reads as zero.
