Jumper Jp13, Oscillator Source Select; Jumper Jp14, Dts/Rts Select; Jumper Jp15, Spi/Sci Bootloader Select - Spectrum Digital TMS320LF2407 Technical Reference

2.11.13 Jumper JP13, Oscillator Source Select

Jumper JP13 is used to select the source of the TMS320LF2407 Clockin. Jumper
position 1-2 selects the onboard oscillator. If position 2-3 is used the clock is from pin
31 on the Control connector P4. The table below shows the positions and their
functions.

2.11.14 Jumper JP14, DTS/RTS Select

Jumper JP14 is used to select the DTS or RTS signal for interrupts to the DSP. If
position 1-2 is selected the DTS signal is used to interrupt the DSP. Using position 2-3
allows the RTS signal to interrupt the DSP. The table below shows the positions and
their functions.

2.11.15 Jumper JP15, SPI/SCI Bootloader Select

The jumper JP15 allows the user to select the source of the on chip bootloader. The
user can either select the SPI or SCI resource on the TMS320LF2407. Using position
1-2 selects the SPI as the bootloader source. The 2-3 position allows the SCI to be
used as the source. The table below shows the positions and their functions.
