Boot Mode and Bypass Mode Select Jumpers
(JP9-JP12)
The ADSP-21992 supports different boot modes, which are controlled by
the three dedicated hardware boot mode control pins (
and ). These modes can be selected by the configuration of the
BMODE0
three 2-pin jumpers (
jumpers is open, whereby no boot mode is selected.
The DSP provides a user-programmable (1x to 32x) multiplication of the
input clock, including fractional values, to support 128 external-to-inter-
nal (DSP core) clock ratios. The
PLL configuration register, specify the PLL multiplication factor at reset.

SPI EEPROM Enable Jumpers (JP13, JP14)

A socket is available on the ADSP-21992 EZ-KIT Lite board for an 8-pin
SPI Serial EEPROM, such as the Microchip 25LC640, which is used for
booting and/or data storage.
