2.11.16 Jumper JP16, Booten Select

The EVM320LF2407 has the ability to load code from an external serial EEPROM via
the on chip boot loader or the RS-232 serial link. To use the bootloader function the
DSP must be in microcontroller mode (JP6). For serial ROM boot loading the SPI is
routed to the serial ROM (JP4), and JP16 must be in the 2-3 position. JP15 should be
set to SPI. For RS-232 boot loading JP4 is a "don't care". JP6 is again in
microcontroller mode. JP15 is set to SCI. Using position 1-2 disables the on chip serial
boot loader. The table below shows the positions and their functions.

2.12 Status LEDs

The TMS320LF2407 EVM has three status light emitting diodes. Two of these are
under software control. DS3 is 'on' when power is applied. These are shown in the table
below.

2.13 User Programmable LEDs

The EVM320LF2407 has four user programmable light emitting diodes. These LEDS
are programmed by writing a binary values to address 0x000C in I/O space. The table
below shows the values to turn on the LEDs.
