SPI0 quad slave mode

Hi folks,

after some days of unsuccessful tries to get a BF707 to receive SPI0 data in quad slave mode, my last hope is that someone else knows more than me.
There are statements in the datasheets and the hardware manuals that quad mode SPI is only possible on SPI2, but there are also other statements that the BF70x supports quad SPI on SPI0 AND SPI2. Please let me know, what is true. Thanks kms
