1. Introduction
Atom is intended to be "the smallest particle that cannot be further divided", and atomic operation is "one or more operations that cannot be interrupted ". It is a little complicated to implement atomic operations on a multi-processor. In this article, let's talk about how the Intel processor and Java implement atomic operations.2. Definition of Terms

formula (refresh time formula):
TWWDG = T_max-t_min
= 4096 * (2^WDGTB) * (wwdg_cfr[6:0]-0x3F)/36 (US)
= 4096 * (2^WDGTB) * (wwdg_cfr[6:0)-/36 (US)
And because wwdg_cfr[6:0] value range is: 0~127,
(wwdg_cfr[6:0]–63) >0,
So
1
And because a 6-bit binary x[5:0] value range is 0~63,
1
So
The above formula can be expressed as:
TWWDG = 4096 * (2^WDGTB) * (t[5:0]+1)/36 (US)
(4) According to the above formula, can calculate the timing range of WWDG:
WDGTB (counter divider value)
