Description

These bits specify the number of consecutive switching cycles with OCP triggered that must

occur before the CS_OCP flag is set.

512 switching cycles

These bits set the CS_OCP flag debounce time. The debounce time is the minimum time that

the CS signal must be continuously above the CS OCP threshold before the flag triggers an

action. This action is programmed in Register 0xFE04, Bits[3:0].

Description

CS1_A/CS1_B OCP

ignored

R/W

Setting this bit causes the CS1_A/CS1_B OCP comparator output to be ignored. The flag is

always cleared.

These bits specify the blanking time. During this time, the CS1_A OCP/CS1_B OCP comparator

output is ignored. The blanking time is measured from the rising edge of OUT1, OUT2, OUT5, or

OUT6 (programmed in Register 0xFE6B and Register 0xFE6C).

These bits set the CS1_A_OCP/CS1_B_OCP flag debounce time. The debounce time is the

minimum time that the CS1_A/CS1_B signal must be continuously above the threshold before

the flag triggers an action. This action is programmed in Register 0xFE00.
