*6-1: The current source of the CP pin operates when the voltage of FB1 exceeds the threshold voltage as shown in the

table.

*6-2: The current source of the CP pin operates when the voltage of FB2 falls below the threshold voltage as shown in the

table.

* 6-3: The timer latch of FB1 is disabled when the CS1 voltage is below the threshold voltage as shown in the table.

* 6-4: The timer latch of FB2 is disabled when the CS2 voltage is above the threshold voltage as shown in the table.
