CSR LPT SPI programmer (CSR8645, CSR8670)

If you have no CSR USB SPI programmer, but a 'real' LPT port (printer port), the CSR can also be programmed via LPT-SPI.

A minimum circuit is shown in the following diagram, this works for modules of the CSR86XX series and also for others. The levels are designed for 1.8V. Tested with a CSR8645 module.
