dsPIC33CH512MP206 Slave ADC Oversampling Filter count

Hi Everyone,
 
I was wondering if someone could help clarify something for me before I commit to a big design descision...
 
http://ww1.microchip.com/...-Sheet-DS70005371D.pdf
 
In the data sheet for the dsPIC33CH512MP508 family, it has conflicting information on the above. In the body text on page 373, it states that the slave ADC only has two oversampling filters (and two comparators for that matter), then on the next page in Figure 4-18 it clearly shows the module having four digital filters (also four comparators). I've checked the silicon errata and data sheet clarification document for the part as well and the data sheet part has no entries.
 
Also, if I create a slave core project for the dsPIC33CH512MP206 and look at the SFRs, there are indeed listed memory mapped registers for ADFL2DAT and ADFL3DAT.
 
None of this is conclusive either way from my perspective, but I would have thought that the module would have at least as many oversampling filters as it has ADC cores.
 
Any help or advice anyone could give would be greatly appreciated.
 
Cheers,
Antony

    There are 4 ADC CMPs. The DS will eventually get fixed.

    Hi spdmtl,
     
    Thanks for the reply, but I was already confident on there being 4 CMPs, what I was asking about was the digital filters...
