If glitching is unacceptable in an application, 1.8 V could be supplied externally. Alternatively, adding a current-limiting resistor (for example, 470 Ω) in series with these pins and any external driver could be considered to limit the potential for degradation to the pin and/or external circuitry.

There is no power-sequencing requirement when using an external 1.8-V supply. However, if the 3.3-V transistors in the level-shifting output buffers of the I/O pins are powered before the 1.8-V transistors when extract texas instrument mcu tms320f2812pg code, it is possible for the output buffers to turn on, causing a glitch to occur on the pin during power up.

To avoid this behavior, power the V_DD pins before or with the V_DDIO pins, ensuring that the V_DD pins have reached 0.7 V before the V_DDIO pins reach 0.7 V.

The peripheral – I/O multiplexing implemented in the device prevents all available peripherals from being used at the same time. This is because more than one peripheral function may share an I/O pin to crack ti microcontroller tms320f28032 flash memory. It is, however, possible to turn on the clocks to all the peripherals at the same time, although such a configuration is not useful. If this is done, the current drawn by the device will be more than the numbers specified in the current consumption tables.
