microcontroller (8051_REGIN). Jumper J9 allows the 8051_REGIN supply to be sourced from either the
Vu+_EXT binding post (J6), +5V binding post (J3) or VD+_EXT binding post (J5).

With a jumper connection on J18 (AUTO-BOOT ENABLE), the CS5463 operates in auto-boot mode and
the CDB5463U board operates as a stand-alone system without attaching it up to a PC. When in auto-
boot mode, a hardware reset (press on S1) will cause the CS5463 to boot up using the serial data from
the serial EEPROM on the board (U10). When the CS5463 is in auto-boot mode, the SPI connections
