GP LOOK-UP TABLES (LUT)
The AD9927 is equipped with a look-up table for each pair of
consecutive GP signals when configured as outputs. GP1 is
always combined with GP2, GP3 is always combined with GP4,
GP5 is always combined with GP6, and GP7 is always combined
with GP8. The external GPO outputs from each pair can output
the result of the LUT or the original GP internal signal.

Figure 76. Internal LUT for GP1 and GP2 Signals
Address 0x79 dictates the behavior of the LUT and which
signals receive the result. Each 4-bit LUT_FOR_GPxy register
can realize any logic combination of GPx and GPy. For example,
Table 43 shows how the register values of LUT_FOR_GP12 [11:8]
are determined. XOR, NAND, AND, and OR results are shown,
but any 4-bit combination is possible. A simple example of XOR
gating is shown in Figure 77.

Field Counter and GPO Limitations
The following is a summary of the known limitations of the
field counters and GPO signals that dictate usability.
The field counter trigger (PRIMARY_ACTION and
SECONDARY_ACTION registers, Address 0x70) is self-reset
at the start of every VD period. Therefore, there must be one
VD period between sequential programming to that address.
If GP*_PROTOCOL = 1, it must be manually reset to
GP*_PROTOCOL = 0 one VD period before it can be
used again. If manual toggles are desired in sequential fields,
the MANUAL_TRIG register should be used in conjunction
with GP*_PROTOCOL = 1.
