Aside from the manpage DS1921, only the sources in
module/owlib/src/c/ow_1921.c. Be aware this is unchartered territory and
not well tested.

The date when the current mission was started.

The idea is to write *anything* to mission/easystart, then the following
happens:
* all memory is cleared
* clock is stopped
* no rollover, no delay, temp alarms on is setup
* pending alarms are cleared
* a new mission is started

Minutes between samples. Writing a positive value starts a new mission,
writing a negative value stops the current mission.

This is controlling the EM bit in the control register directly.

Writing 0/1 starts/stops a mission, reading returns the MIP bit in the
status register.

No, you have to concatenate the memory pages yourself.
