Hi all, I am using an external clock to transmit serial data from a VC33 to a CPU but it is occasionally loosing a data word. The XSR EMPTY bit 3 of the serial port global control register seems to stay low all the time (ie transmit shift register empty) even if I stop the ext

I have an application where I need to use a DSP in conjunction with an 8051-based processor. I foresee using either DMA or a dual-port- ram as the interface between the DSP and the processor. The vc33 is adequate for this application, but the University kit does not appear to provide
