MityDSP Hardware Release Notes

1. Updated a cross-clock domain metastability issue on the latest_sample register to the DSP. This should avoid any issue with the emif sitting on that register. Bugzilla #2019

1. The I2C core was rewritten to support devices requiring 16 bit subaddressing (for example, larger PROMS such as the FM24CL64B). Because of the scope of the rewrite, the original i2c core (version 1.X) was preserved for legacy programs and to avoid regressions. Version 2 and above will be captured in the I2C2 netlists.
2. Support for 10 bit slave addressing is included, but untested (no hardware platforms available at the time of this delivery).
3. The number of bytes that may be transferred in one continuous cycle is now 65535. However, you may essentially extend that infinitely by controlling the issue of the stop control bit of the bus protocol. There will be a small delay between commands, however.
4. Clock stretching/extension is not yet supported.
5. Slave mode is not supported.

1. Add capability to send an arbitrary command (including configuration word) to device. Supports software reset.

   • Power Control
   • Backlight Control
   • Backlight Dimming

1. Offset both Transmit and Receive buffers by 2 bytes in order to support direct DMA transfers from the DSP (without addition buffer copies). This was required as the DSP required certain IP layer fields to be 4 byte aligned in order to avoid additional buffer copies. Due to the nature of this change, version 2.00 of the ethernet core is no longer compatible with prior MDK versions of software. This change allows nearly a 3x improvement in ethernet stack performance and was deemed necessary to support new MityDSP realtime applications. Bugzilla #1096
