et the external interrupt input pull-up resistor built.
Clock speed prescaler and clock counter mode register values together determine the LED blink rate. A 12.8 MHz internal oscillator clock, to obtain 3.2 MHz bus frequency, each cycle is equal to 0.3125 s. The prescaler value is selected as 64, the time counter mode register can be calculated as 50 times a cycle timer period (in milliseconds). For example, to get the blink rate 1s, should be time counter mode is set to 50000, or hexadecimal
