Table 32. Register 0xFE06—Flag Reenable Delay, VDD_OV, and FLAGIN Configuration

Bits

Bit Name

R/W

Description

These bits specify the global delay from when a flag is cleared to the soft start process.

Bit 7

Bit 6

Typical Delay Time

250 ms

500 ms

1 sec

[7:6]

Flag reenable delay

R/W

2 sec

VDD_OV flag ignore

R/W

This bit enables or disables the VDD_OV flag.

0 = VDD_OV flag enabled. When there is a VDD overvoltage condition, the flag is set and the

part shuts down. When the flag is cleared, the part restarts.

1 = VDD_OV flag is always cleared.

VDD_OV flag

debounce

R/W

This bit sets the debounce time for the VDD_OV flag.

0 = 500 μs debounce time.

1 = 2 μs debounce time.

[3:2]

FLAGIN action

R/W

These bits specify the action to take when the FLAGIN flag is set.

Bit 3

Bit 2

FLAGIN Action

None

Disable PWM outputs in Channel A

Disable PWM outputs in Channel B

Disable all PWM outputs (Channel A, Channel B, and Channel C)

R/W

These bits specify the action to take after the FLAGIN flag is cleared.

Bit 1

Bit 0

Action After FLAGIN Is Cleared

After the reenable delay time, the PWM outputs are reenabled using the soft

start process

The PWM outputs are reenabled immediately without a soft start

A PSON signal is needed to reenable the PWM outputs

[1:0]

Action after FLAGIN

is cleared

A PSON signal is needed to reenable the PWM outputs

Register 0xFE07 selects flags to be blanked during soft start. When a flag is blanked, the flag is set but no action takes place. During the soft

start of any channel, the following flags are always blanked: FLAGIN, OTP1, OTP2, and ACSNS. During the soft start of Channel A, these

flags are also blanked: REVERSE_A and UVP_A. During the soft start of Channel B, these flags are also blanked: REVERSE_B and UVP_B.

CS_OCP blanking

R/W

0 = blank CS_OCP flag during Channel C soft start.

1 = do not blank CS_OCP flag.

OVP_B blanking

R/W

0 = blank OVP_B flag during Channel B soft start.

1 = do not blank OVP_B flag.

OVP_A blanking

R/W

0 = blank OVP_A flag during Channel A soft start.

1 = do not blank OVP_A flag.

CS2_B_OCP blanking

R/W

0 = blank CS2_B_OCP flag during Channel B soft start.

1 = do not blank CS2_B_OCP flag.

CS2_A_OCP blanking

R/W

0 = blank CS2_A_OCP flag during Channel A soft start.

1 = do not blank CS2_A_OCP flag.

CS1_B_OCP blanking

R/W

0 = blank CS1_B_OCP flag during Channel B soft start.

1 = do not blank CS1_B_OCP flag.

CS1_A_OCP blanking

R/W

0 = blank CS1_A_OCP flag during Channel A soft start.

1 = do not blank CS1_A_OCP flag.
