VDD3P3_RESPONSE REGISTER

This register instructs the device on actions to take due to a VDD overvoltage fault condition.

Table 65. Register 0xFE03—VDD3P3_RESPONSE

Bits

Bit Name

R/W

Description

RSVD

Reserved.

Save first flag ID

to EEPROM

R/W

1 = save the first flag ID to EEPROM when the device shuts down.

0 = do not save the first flag ID to EEPROM when the device shuts down.

[5:3]

Retry wait time

R/W

These bits determine the retry wait time before the next soft start. Each LSB = 588 ms.

Reload EEPROM

R/W

1 = reload the contents of EEPROM.

0 = do not reload the contents of EEPROM.

Debounce time

R/W

1 = 2.56 μs.

0 = 660 μs.

Ignore VDD OV

R/W

1 = ignore the VDD 3.3 V overvoltage fault.

0 = do not ignore the VDD 3.3 V overvoltage fault.
