Wake From Sleep on UART Input
I want to take advantage of low power sleep modes, but I'm having trouble determining if PSoC3 can wake up from sleep or hibernate upon receiving data on the UART.
My project requires that I sample data at 30 ksps and send to PC via UART. Once completed, I want the PSoC to go into a low power mode until a timer tells it to sample more data. During this idle state I want the PSoC to be able to receive data for user instructions (i.e. , stop program, change settings, etc.). Can the PSoC be moved out of sleep mode on UART input? What type of UART configuration/settings should I use?
