SIxMODE and SIxMODEX contain bits
that can be used to determine the machine mode type.
These bits should NOT be used for this purpose any more,
instead the HCPVMODE macro should be used to test for
machine modes: System-370, ESA/370, ESA/XC.
XA/370 machines are considered to be ESA/370.

used and SIxRRF is set. Valid in
all VMDBKs.
..1. .... SI12NDVR X'20' SI12NDVR Indicates Rguest

.... ...1 SI1MCDS X'01' SI1MCDS If MCDS facility is
installed and ESA/370 mode is
enabled, then the guest is in

UNTIL 3.333 MILLISECONDS HAS BEEN
ACCUMULATED, AT WHICH POINT THE
GUEST INTERVAL TIMER IS
DECREMENTED AND THE RESIDUE
COUNTER IS REDUCED BY 3.333
MILLISECONDS. SOFTWARE USES THE

Space-switch-control bit was on
00D1 209 Bitstring 1 SI1SSCT2 when a space switch program
interruption occurs, the old

control bit is saved in the
high-order bit of SIxSSCTL. The
remaining bits of SIxSSCTL and
SIxSSCT2 are set to 0.
