In the MSP430 microcontroller, one clock cycle = the inverse of the MCLK crystal oscillator. If the MCLK is 8MHz, then one clock cycle is 1/8us. One machine cycle = one clock cycle, that is, each acti...
When USB is working, the system clock must be configured to at least 48MHz. Does that mean that the power consumption of the CPU is about 12mA when it is running normally? This current is too high for...
