Yes, when CmdIgnSts transitions to IGN_OFF, it is necessary to save the ACN_Failed_DrivingCycle internal variable in the internal non-volatile memory. This allows the data value to be retrieved at the next KEY ON event. By doing so, the system ensures that the variable's value is persistent across ignition cycles.

Design FIR Low Pass filter using I-type linear phase, according to the parameters as follow, by matlab code:
Sure! Here is the Matlab code for designing an I-type linear phase FIR low pass filter according to the given parameters:
```
% Define filter parameters
Fs = 1000; % Sampling frequency
Fpass = 100; % Passband frequency
Fstop = 150; % Stopband frequency
Ap = 0.1; % Passband ripple (dB)
Ast = 80; % Stopband attenuation (dB)
% Normalize frequencies
Wpass = 2*Fpass/Fs;
Wstop = 2*Fstop/Fs;
% Determine filter order
N = ceil((Ast-8)/(4.57*(Wstop-Wpass))+1);
% Design filter using firpm function
b = firpm(N, [0 Wpass Wstop 1], [1 1 0 0], [10^(-Ap/20) 10^(-Ast/20)]);
% Plot magnitude and phase response
freqz(b,1,Fs)
```
In this code, we first define the filter parameters including the sampling frequency, passband frequency, stopband frequency, passband ripple, and stopband attenuation. We then normalize the frequencies to be between 0 and 1 for use with the firpm function. The filter order is determined using the Kaiser formula, and the filter is designed using the firpm function with a window that transitions from 1 in the passband to 0 in the stopband. Finally, we plot the magnitude and phase response of the filter using the freqz function.
Note that the resulting filter coefficients are stored in the variable b, which can be used to filter a signal using the filter function in Matlab.
FSMS_transitions
FSMS_transitions是什么?
FSMS_transitions是一个缩写,它代表有限状态机(Finite State Machine)的状态转移。在有限状态机中,每个状态都有一个有限的状态集合,并且状态之间的转移是通过输入来触发的。FSMS_transitions是指这些状态之间的转移规则,它描述了在输入下状态从一个状态转移到另一个状态的方式。这些转移规则可以用图形的方式呈现出来,通常称为状态转移图。在计算机科学中,有限状态机被广泛用于描述计算过程和控制流程。
