- Page 7 AN231K04-DVLP3 – AnadigmApex Development Board Other Features Pins The 3 reference pins on the dpASP device – VMR (+1.5V), VREFP (+2.5V) and VREFN (+0.5V) – have been connected via the p.c.b. tracks to the 3 holes to the right of the dpASP (see figure 2). In addition, VMR is available on the inner ring or inner two rows of pins that are adjacent to the analog I/Os.
- Page 8 ® Anadigm recommends that our customers use their own processor development boards and connect via jumper J5 to Anadigm’s dpASP for fully dynamic control of the dpASP, in preference to re-engineering the digital section of this development board. FLASH Storage In FLASH storage mode, all primary configurations sent to the development board are stored in the FLASH of the PIC.
