Philips Pronto RU950 hex codes for Toshiba Regza RV635 television, using CT-90326 remote (so, I suppose, other Toshiba TVs using the same remote will behave the same) is mostly covered by the Philips Pronto's Toshiba Codeset 0580, but it has a few errors and there are undocumented discrete on, off and source selection codes.
The order of this listing is from top to bottom of the Toshiba remote control:

Cycle source: 900A 006D 0000 0001 40BF 14EB (See below for discrete codes)
Toggle on/off: 900A 006D 0000 0001 40BF 12ED (See below for discrete codes)
Freeze: 900A 006D 0000 0001 40BF 22DD (Note that Codeset 0580 is wrong)

I have tried all other codes between 00FF and 7D82 and found no response. I didn't bother testing above 807F as none of the known codes are in this space.
