For example, if the segment size is 10,000 readings, the terminal
and base addresses would be:
start address = 524,287 - 9,999 = 514,288
514,288 / 4 = 128,572 = 1F63C
16
terminal address = 254 + 1 (since 128,572 > 65,535)
base address = F63C (the ’1’ is part of the terminal address: 254 +
1)

5. Enable memory to be written to.
A. Enable data to be written to digitizer memory and enable the address
counter by setting memory control register (base + 21

) bits 2 - 0 to
’1 0 1’.
Initializing and
Initiating the
Timebase
Processor
The second step in re-initiating the digitizer is initializing and initiating the
timebase processor. The timebase processor must be initialized each time
the pre-arm reading count, post-arm reading count, or sample rate is
changed.
