If the user sampling pulse (uc_loguserpulse_clk100m_reg) is smaller than the minimum setting value of the logging cycle
timing below, it will not work properly. ( Page 193 Timing generator (tg2_top))
After enabling (1) the user sampling pulse (uc_loguserpulse_clk100m_reg), logging processing is performed in the logging
part. During logging processing, even if the user sampling pulse (uc_loguserpulse_clk100m_reg) is enabled (1), it is ignored
by the logging part. The operation when the pulse interval is set below the minimum setting value is shown below.
