-The infamous EUSART bug had been found on a PIC18F4550 during the development of the MBHP_USB_PIC module. Unfortunately it turned out, that many PICs (such as the [[mios_pic18f4620|PIC18F4620]]) were affected by this bug as well.

 For detailed infos, how the bug has been found, please read the detailed report at the [[http://www.ucapps.de|MBHP_USB_PIC]] page.
-Since there was no adequate software workaround available for this silicon bug, it made the old chip revisions nearly useless for MIDI applications: zero bytes were sporadically inserted into the MIDI Out stream, so that the MIDI protocol was violated. As a hardware workaround for this issue, a [[iic_modules|MBHP_IIC_MIDI]] module was used with minimal configuration (MIDI Out only).

 Meanwhile the bug has been fixed by Microchip.
