*1 The latched mode operates when the voltage of FB1 or FB3 exceeds the threshold voltage as shown in the table.
*2 The latched mode operates when the FB2 voltage falls below the threshold voltage as shown in the table.
*3 The timer latch of FB1 is disabled when the CS1 voltage is below the threshold voltage as shown in the table.
*4 The timer latch of FB2 is disabled when the CS2 voltage is above the threshold voltage as shown in the table.
