Time stamp event push - When a logic high is written to this bit a
time stamp event is pushed onto the event FIFO.
The time stamp value is the time of the write of this register, not the
time of the event read.
The time stamp value can then be read on interrupt via the event
registers.
Software should not push a second time stamp event onto the event
FIFO until the first time stamp value has been read from the event
FIFO (there should be only one time stamp event in the event FIFO
at any given time).
This bit is write only and always reads zero.
