What does the apple bell cup mean?

Apple Clock cup stands for time zone abbreviation, and cup stands for time zone abbreviation of the American city Cupertino.

It is the beat pulse or T period, and it is the most basic unit of processing operation. In the microprogrammed controller, the time sequence signal is relatively simple, and the two-level system of beat potential and beat pulse is adopted. In other words, it only needs one beat potential, and the beat potential contains several beat pulses (clock cycle).

The beat potential represents the time of a CPU cycle, and the beat pulse divides a CPU cycle into several smaller time intervals. These time intervals can be equal or unequal, as required.

The external clock is used for communication-related settings. For example, a serial port of 232 is needed, the external clock should be 1 1.0592M, 22, 1 184M, and the usb transmission should be 6M, 12M, 48M and 96M. The internal clock is used to enhance the computing power of the chip. The internal clock is faster than the external clock and can be set.
