the current resolution of any BTIDriver device (including the OB2) can be read
with
BTICard_TimerResolution
.
Each of the cores of the OB2 maintains lockstep time through a broadcast system
time message and shared oscillator. The default timer rollover is one year, but is
user adjustable to account for leap years.
BTICard_CardReset
does not reset the core timer. A user must call
BTICard_TSMReset
to reset the TSM configuration and timer. This prevents a
call to BTICard_CardReset on one core from interfering with the time-stamps
used by a different core on the same device.
