As mentioned in the errata, this is only temporarily not available. This should be available in a future release of the Creator.
I use Capsense CSD component and 8 bit PRS. In my opinion it works correctly.
I use PSoC Creator 1.0 Beta 4.1 (220.127.116.1149), CSD component CapSense_v1_30 and Cy8C3866LTI-030 ES2 chip.
