4.6 Status Model
4 – 63
In addition to monitored events from the TECR, several discrete
events are directly defined in TEEV without corresponding real-time
condition bits in the TECR. These are:
Weight
Bit
Flag
1024
10
TEC OPEN
2048
11
RUNAWAY
TEC OPEN : Indicates the TE tripped o
ff
due to open circuit.
OPEN : Indicates the TE tripped due to thermal runaway.
4.6.5.3 TEC controller status enable (TESE)
This is a 16-bit wide register that masks the TEEV register. The
logical OR of the bitwise AND of TEEV and TEEN produces the
TESB message in the Status Byte register (SB).
