example 1
[0068] The value configuration of each register in the storage group is as follows, and the configuration value of the register indicates the corresponding condition. Wherein, the valid condition is expressed as 1, and the invalid condition is expressed as 0.
[0069] Table 1 Example 1 configuration value list
[0070] register name condition configuration value condition register 0 condition 0 0 condition condition 1 Condition 1 0 condition register 2 Condition 2 0 condition register 3 Condition 3 1 condition register 4 Condition 4 0 condition register 5 Condition 5 0 boot register start condition 1
[0071] According to the above configuration, the reset state machine jump process is as follows Image 6 shown.
[0072] Condition 3 is valid in the jump process. After the reset state machine is started, it jumps directly from state 0 to state 2, and then returns to the initial state after passing throu...

[0077] According to the above configuration, the reset state machine jump process is as follows Figure 7 shown.
[0078]In this jump process, condition 0 is valid. After the reset state machine is started, it jumps from state 0 to state 1, state, state 3, state 4, state 5 and state 6, and then returns to state 0. The above reset process means that the corresponding modules work after the output is reset from state 0 to state 5. When the module corresponding to state 6 is released, the previously reset and released modules are reset again to ensure that the whole is reset and in a certain state.
[0079] Please refer to Figure 8 , to facilitate the understanding of the present disclosure, an embodiment of the present disclosure also provides a software-configurable reset method, which is applied to such as figure 1 The shown reset device resets the chip. The reset device includes a reset state mach...
