Field Bits Type Description
TCV0 [1:0] rh Temperature Compensation 0 Value
This bit field indicates the compensation value that is
generated for the temperature compensation logic 0.
TCV0 is fed to the temperature compensation logic 0
outputs while bit TCS0 = 0.
00
B
Minimum driving strength required, i.e. very
low temperature.

B
Maximum driving strength required, i.e. very
high temperature (default after reset).
TCE0 3rwTemperature Compensation 0 Enable
0
B
Temperature compensation logic 0 is
deactivated (default after reset). The port
drivers are at maximum driver level.
1
B
Temperature compensation logic 0 is active.
THCOUNT is periodically updated.
TCC0 [5:4] rw Temperature Compensation 0 Control
This 2-bit value is fed to the temperature
compensation logic 0 outputs while bit TCS0 = 1.
Encoding of TCC0 is equal to TCV0.
