OEM password; read-only otherwise.
Reserved – do not write; reads undefined.
Numerical constants for external calibration; writeable using
the OEM password; read-only otherwise.
Reserved – do not write; reads undefined.
General-purpose NVRAM; writeable using the OEM password;
read-only otherwise.
Real time analog parameter data.
Reserved – do not write; reads undefined.
Control and status bits.
Bits [7-6] control the use of the RS0 and RS1 inputs and the
SRS0 and SRS1 register bits.
Alarm status bits; read-only.
Reserved – do not write; reads undefined.
Warning status bits; read-only.
Additional control and status bits.
Reserved – do not write; reads undefined.
OEM password entry field. The four-byte OEM password
location can be selected to be 78h-7Bh (120-123) by setting
OEMCFG5 bit 2 to 0 (default) or 7Bh-7Eh (123-126) by setting
OEMCFG5 bit 2 to a one.
Vendor specific. Reserved – do not write; reads undefined.
User-writeable EEPROM. General-purpose NVRAM.
Bit = 0: Corresponding alarm not masked.
Bit = 1: Corresponding alarm masked.
Bit = 0: Corresponding warning not masked.
Bit = 1: Corresponding warning masked.
Reserved – do not write; reads undefined.
End-user control and status bits.
Bits [2:0] of this register control the QGPO reset output (pin 2)
If OEMCFG3 bit 7 is set to 1.
