Page 15: Embedded Rlink
The functionalities of this embedded version of RLink v3.3 are the same as the standalone version. The desired communication protocol can be configured via the jumpers embedded on the REva. The next paragraphs describe configurations for the protocols used by the REva daughter boards. -
Page 16: Daughter Boards
Do not insert 1.8V daughter boards before the RLink and the REva have been broken apart. As ISP/ISD signals are connected directly between the motherboard and the RLink, it is mandatory to break these connections before using 1.8V target devices, as the RLink cannot work at this voltage. -
