BACKGROUND_CRC_STATUS

Background CRC status. Read only status bit. When this bit is high, this signifies

that a background CRC of the memory map has failed and a memory bit may

have inadvertently flipped.

0x0

0: normal.

1: background CRC error activated.

[6:4]

Reserved

Reserved.

0x0

IREF_FAULT

External IREF resistor fault status. Read only status bit. When this bit is set, a fault

has been detected with the external reference current generation resistor, and

the internal resistor has been switched to avoid damage to the device.

0x0

0: normal.

1: IREF fault activated.

NEGATIVE_CHANNEL0

Negative Voltage Channel 0 status. Read only status bit. When this bit is set, a

fault has been detected due to a negative voltage being multiplexed to the

MUX_OUT pin when monitoring Channel 0.

0x0

0: normal.

1: negative Channel 0 activated.

OVER_TEMP

Overtemperature fault status. Read only status bit. When this bit is set, an

overtemperature fault occurrence has been detected. An overtemperature fault

occurs when the internal die temperature reaches approximately 145°C. A reset

command must be issued to the device to clear this bit.

0x0

0: normal.

1: overtemperature activated.

TEMP_WARNING

Overtemperature warning status. Read only status bit. When this bit is set, an

overtemperature warning occurrence has been detected. An overtemperature

warning occurs when the internal die temperature reaches approximately 125°C. This

bit is automatically cleared when the internal die temperature returns below 120°C.

0x0

0: normal.

1: temperature warning activated.
