AFAIR it has around 150 registers, many of them 16 or 32 Bit in size.

In DVB-S mode, only few of the registers are used. It is basically like
in older STV0299, you set the registers and wait until the demod is
locked. In DVB-S2 mode, you have to build several loops in software,
together with the bigger amount of registers (and much more complicated
addressing scheme) it makes things a bit less easy.
