3.10 Reset Switch

There are three resets on the TMS320VC5509A EVM PLUS. The first reset is the
power on reset. This circuit waits until power is within the specified range before
releasing the power on reset pin to the TMS320VC5509A.
External sources which control the reset are push button S1, and the on board
embedded USB JTAG emulator.
3.11 Wake Up Switch
S4 is a "Wake Up" switch to the DSP. When the DSP is in idle mode the switch can
generate an interrupt to wake up the DSP. See the section on the CPLD Interrupt
register to enable interrupts for the "Wake Up" switch
