register may be written by the mttbl or the mttbu instructions, see
Section 3.9.4, “Time Base Facility (TB)
.”
Refer to
Section 3.8, “VEA Register Set — Time Base (TB)
Section 3.9.4, “Time Base Facility (TB)
” for more information on reading and writing the TBU and TBL registers.

Time Base Reference Registers (TBREF0 and TBREF1)
Two reference registers (TBREF0 and TBREF1) are associated with the lower part of the time base (TBL).
Each is a 32-bit read/write register. Upon a match between the contents of TBL and the reference register,
a maskable interrupt is generated.
