are within the working space defined by the parameters UMINI and
UMAXI, and VMINI and VMAXI (and WMINI and WMAXI for
systems processing three-dimensional images), the Target
Address Valid flag TVAL for that device is LOW. This flag will go
HIGH on the clock in which the current target address outputs fall
outside the defined region, which must fall inside the target area
defined by UMIN, UMAX, etc. Since each TMC2302A device is
programmed with distinct MINI/MAXI parameters and generates a
separate TVAL flag, the user may define separate two or three-
dimensional target space windows for each device. TVAL can be
delayed up to seven clock cycles after the nominal sequence
shown in Table 4 by the pipeline delay parameter PIPTVA. See the
Device Configuration and Control Parameters section.
End of Dimension.
During the last pixel interpolation walk of a row
(X/U device), the last row in a page (Y/V device), or the last page in
a three-dimensional transform (Z/W device), the flag ENDD goes
HIGH for the entire walk, indicating End of the transform in that
dimension. It remains LOW otherwise. This output can be delayed
up to seven clock cycles after the nominal sequence shown in
Table 4 by the pipeline delay parameter PIPEND. See the Device
Configuration and Control Parameters section.
Done.
On the last clock cycle of the current image transform, the
DONE flags on all TMC2302As go HIGH for one clock cycle. On
the next clock cycle, all devices output the first addresses and
control signals for the next image transform. If SYNC is LOW, the
IMS system halts. If SYNC is HIGH, operation continues without
interruption. See “SYNC,” in the Controls section. This flag can be
delayed up to seven clock cycles after the nominal sequence
shown in Table 4 by the pipeline delay parameter PIPDON. Also
see “PFLS,” in the Device Configuration and Control Parameters
section.
