The recommended power-on sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
During reset, the JTAG interface should be held in a high-impedance state to prevent any unwanted data from being written to the device. This can be achieved by using a JTAG controller with a built-in reset detection feature.
The maximum clock frequency is 50 MHz, but it's recommended to operate the device at a frequency of 40 MHz or less to ensure reliable operation and minimize power consumption.
The TMS320C50PGE57 has a built-in watchdog timer that can be enabled and configured using the watchdog timer control register. The watchdog timer can be used to reset the device in case of a software fault or hang.
The IDLE pin is used to indicate when the device is in an idle state, which can be used to reduce power consumption. When the IDLE pin is asserted, the device enters a low-power state, and the clock signal is gated off.
