RISC-V vsip CSR Register

What This Field Controls

• - Without AIA, bits 16 and above within VSXLEN are platform-use WARL pending bits as implemented, while bits 15:14 are read-only zero. For AIA causes 14-63, hideleg[i]=1 makes vsip[i] an alias of sip[i]; otherwise hvien[i]=1 makes it an alias of hvip[i]; if both are zero it is read-only zero. RV32 accesses AIA bits 63:32 through vsiph.

Common Values

This field is better understood together with surrounding context than as a fixed memorized enumeration.

What This Field Controls

• - With Shlcofideleg and hideleg[13]=1, this aliases sip.LCOFIP; otherwise it is read-only zero under the base H rules. Under AIA, hideleg[13]=0 and hvien[13]=1 instead make it an alias of hvip[13]; if both are zero it is read-only zero.

Common Values

This field is better understood together with surrounding context than as a fixed memorized enumeration.

What This Field Controls

• - Standard reserved bits that read as zero.

Common Values

This field is better understood together with surrounding context than as a fixed memorized enumeration.

What This Field Controls

• - Read-only alias of hip.VSEIP when hideleg[10]=1; otherwise read-only zero.

Common Values

This field is better understood together with surrounding context than as a fixed memorized enumeration.

What This Field Controls

• - Standard reserved bits that read as zero.

Common Values

This field is better understood together with surrounding context than as a fixed memorized enumeration.

What This Field Controls

• - Read-only alias of hip.VSTIP when hideleg[6]=1; otherwise read-only zero. hip.VSTIP can combine hvip.VSTIP with the Sstc vstimecmp signal.

Common Values

This field is better understood together with surrounding context than as a fixed memorized enumeration.

What This Field Controls

• - Standard reserved bits that read as zero.

Common Values

This field is better understood together with surrounding context than as a fixed memorized enumeration.

What This Field Controls

• - Writable alias of hip.VSSIP when hideleg[2]=1; otherwise read-only zero. hip.VSSIP is itself an alias of hvip.VSSIP.
