[讨论] 此段代码有什么语法错误么？

[email=always@(negedge]always@(negedge[/email] RESET negedge CLK2M)
if(RESET==0)
begin
CNT1<=0;
else if (V_GENIN == 11)
CNT1<=0;
if (V_GENIN == 01)
CNT1<=CNT1^1;
else
CNT1<=0;
end

[email=always@(negedge]always@(negedge[/email] RESET negedge CLK2M)
if(RESET==0)
begin
CNT1<=0;
else if (V_GENIN == 11)
CNT1<=0;
      else if (V_GENIN == 01)
CNT1<=CNT1^1;
else
CNT1<=0;
end

or

[email=always@(negedge]always@(negedge[/email] RESET or negedge CLK2M)
  begin
if(RESET==0)
CNT1<=0;
   else if (V_GENIN == 11)
CNT1<=0;
   else if (V_GENIN == 01)
CNT1<=CNT1^1;
   else
CNT1<=0;
  end
