3.3 DIP and PushButton Switches
The C6657 Lite EVM has three push button switches and three sliding actuator DIP switches. The RST_COLD1,
RST_WARM1 and RST_FULL1 are push button switches while SW3, SW5 and SW9 are DIP switches. The
function of each of the switches is listed in the table below:
Table 3.17: C6657 Lite EVM Board Switches
Switch
Function
RST_COLD1
Cold Reset Event (RFU)
RST_FULL1
Full Reset Event
RST_WARM1 Warm Reset Event
SW3
DSP Configuration, DSP Boot mode
SW5
DSP Boot mode, PLL setting, PCIe
Mode Selection
SW9
PCIe Enable/ Disable, User Switch
3.3.1 RST_COLD1, Cold Reset
The button is reserved for future use.
3.3.2 RST_FULL1, Full Reset
Pressing the RST_FULL1 button switch will issue a RESETFULL# to TMS320C6657 by
FPGA. It‟ll reset DSP
and other peripherals.
3.3.3 RST_WARM1, Warm Reset
Pressing the RST_WARM1 button switch will issue a RESET# to TMS320C6657 by FPGA. The FPGA will assert
the RESET# signal to DSP and DSP will execute either a HARD or SOFT reset by the configuration in the
RSCFG register in PLLCTL.
Note:
to check the difference between assertion of DSP
RESET# and the other reset signals.
3.3.4 SW3, DSP Configuration
SW3 is an 8 position DIP switch, which is used for DSP configuration. A diagram of SW3 switch (with factory
default settings) is shown below:
