TCS0 7rwTemperature Compensation 0 Source
0
B
Temperature compensation logic 0 is
controlled by the temperature compensation
control hardware.
1
B
Temperature compensation logic 0 is
controlled by software via bit field TCC0.
TCDIV [15:8] rw Temperature Compensation Clock Divider
This value controls the input clock divider for the
temperature compensation logic.
TCV1 [17:16] rh Temperature Compensation 1 Value
This bit field indicates the compensation value which
is generated for the temperature compensation
logic 1. TCV0 is fed to the temperature
compensation logic 0 outputs while bit TCS1 = 0.
00
B
Minimum driving strength required, i.e. very
low temperature.
...
B
...
11
B
Maximum driving strength required, i.e. very
high temperature (default after reset).
TCE1 19 rw Temperature Compensation 1 Enable
0
B
Temperature compensation logic 1 is
deactivated (default after reset). The port
drivers are at maximum driver level.
1
B
Temperature compensation logic 1 is active.
THCOUNT is periodically updated.
TCC1 [21:20] rw Temperature Compensation 1 Control
This 2-bit value is fed to the temperature
compensation logic 1 outputs while bit TCS1 = 1.
Encoding of TCC1 is equal to TCV1.
TCS1 23 rw Temperature Compensation 1 Source
0
B
Temperature compensation logic 1 is
controlled by the temperature compensation
control hardware.
