MCU (mpc8247) can avoid the realtime clock interupt when mcu is busy. so MCU peak of calculation is isochronous with I/O device sample and transmit cycle. use a programmable-counter of sample and transmit cycle . In C language , the function delay of time (ms)(for example timer, delay,sleep) can be realized with no- MCU- interupted mode,because when the timer is arrived ,the programm can guarantee the cpu is free, . reduce the operation of (push pull with stack&heap)...so system will be faster
1. Which MCU in question?
2. I do not see any question in the above text. What is the exact question regarding this above statement?
