But PCM has film-like board and while tuning I'll need to soldered the chip several times. That will destroy the film.
There are some pads near the chip so how can I use them to reprogramm the chip?

A datasheet and a multimeter answers that.

Those pads alongside the flash are what the "instrumented" 96-98 JTECs daughterboards are attached to.
