Detailed Register Description
Conventions
Name of Row
Name of Byte ...................<Read/Write><Volatile><Power-On Value>
Name of Byte ...................<Read/Write><Nonvolatile><Factory-Default Setting>
Name of Byte ...................<Read/Write><Shadowed Nonvolatile><Factory-Default Setting>
Name of Byte ...................<Read/Write><Status><Power-On Value>
Lower Memory
00h
USER EE ..........................<R-all/W-all><Shadowed Nonvolatile><00>
01h
Signal Condition...............<R-all/W-all><Volatile><00> Bit 0 can only be written if Table 01h, Byte DDh, bit
<0> is high. Bits <2:1> control EN2 and EN1, respectively.
02h
→ 39h
Alarms and Warnings ......<R-all/W-Module><Shadowed Nonvolatile><Note*> These registers set the 16-bit
threshold level for corresponding monitor channels. *Note: High alarm and warnings
factory default to FFFFh, and low alarm shut warnings default to 0000h.
3Ah, 3Bh
USER EE ..........................<R-all/W-all><Shadowed Nonvolatile><00>
46h
→ 4Fh
USER SRAM.....................<R-all/W-all><Volatile><00>
50h
→ 57h
Latched Flags ..................<R-all/clear-all><Volatile><00> These are latched flags for corresponding signals.
Any flag is cleared by simply reading it.
58h
→ 5Fh
Masks...............................<R-all/W-all><Volatile><00> These mask bits internally block the signals that drive
the INTERRUPT pin. A low setting causes the corresponding monitor channel to
drive the INTERRUPT pin.
60h
→ 6Dh
Monitor Values .................<R-all/W-all><Volatile><xxxx> These registers are internally updated with the moni-
tor channel’s digital result. They can be read as left-justified 16-bit values.
6Eh
GCS1 ...............................<R-all/W-all><Volatile><xx> These are nonlatched flags, indicating the real-time
digital state of a corresponding signal as well as control bits for particular functions.
