NOTES: (1) DSP56001 programmed for MSB bit first. (2) For 16-bit data connect SWL to Logic 1; For 24-bit data connect SWL to Logic 0.
NOTES: (1) Program TMS320C30 for 32-bit mode. (2) Sample rate on DSP102 and DSP202 may differ. (3) DSP32C may also be used
in this mode, with SSF pins tied LOW. *See Burr-Brown DSP101/DSP102 product data sheet for full description of this ADC.
