If WIPESPD is set accordingly, PIPON controls the wipe operation. When PIPON
changes the wipe operation starts. During this period, the readable PIPSTAT indicates
the ongoing wipe-process. A transition of PIPON from ’0’ to ’1’ triggers the wipe-in. The
wipe-in process stops when the picture reaches its programmed size. When PIPON
changes from ’1’ to ’0’ the wipe-out starts. The wipe-out is finished when the PiP picture
vanishes. Even for multi-picture display wipe operation is possible. A change of PIPON
or WIPESPD during wipe operation has only an effect after the wipe operation has been
finished.

To improve picture sharpness, a peaking filter which amplifies higher frequencies of the
input signal is implemented. The amount of peaking can be varied in seven steps by
YPEAK. The setting ’000’ switches off the peaking. The value ’001’ is recommended as
This value provides a good compromise between sharpness impression and annoying
aliasing. The characteristic for all possible settings is shown in fig. (4-12). The
emphasized frequency depends on the adjusted decimation. The gain maximum is
always located before the band-limit ensuring optimal picture impression.
