Set Global time
Writing a '1' to SGT sets TTOST.WGDT if the node is
the actual Time Master. SGT is reset after one
Host clock period. The global time preset takes effect
when the node transmits the next reference
message with the Master_Ref_Mark modified by the
preset value written to TTGTP.

External Clock Synchronization
Writing a '1' to ECS sets TTOST.WECS if the node is
the actual Time Master. ECS is reset after one
Host clock period. The external clock synchronization
takes effect at the start of the next basic cycle.

Register Time Mark Interrupt Pulse Enable
Register time mark interrupts are configured by
register TTTMK. A register time mark interrupt pulse
with the length of one NTU is generated when the time
referenced by TTOCN.TMC (cycle, local, or
global) equals TTTMK.TM, independent of the
synchronization state.
