Description
This register contains the eight MSBs of the 12-bit t
the top four bits of Register 0x54, which contains the four LSBs of the t
corresponds to 5 ns resolution.
Description
These bits contain the four LSBs of the 12-bit t
bits of Register 0x53, which contains the eight MSBs of the t
5 ns resolution.
1 = PWM modulation acts on the t
0 = no PWM modulation of the t
1 = negative sign. Increase of PWM modulation moves t
0 = positive sign. Increase of PWM modulation moves t
1 = SR signals perform a soft start every time that they are enabled.
0 = SR signals perform a soft start only the first time that they are enabled.
Setting this bit enables the soft start function for the SR signals.
Description
This register contains the eight MSBs of the 12-bit t
the top four bits of Register 0x56, which contains the four LSBs of the t
corresponds to 5 ns resolution.
Description
These bits contain the four LSBs of the 12-bit t
bits of Register 0x55, which contains the eight MSBs of the t
5 ns resolution.
1 = PWM modulation acts on the t
0 = no PWM modulation of the t
1 = negative sign. Increase of PWM modulation moves t
0 = positive sign. Increase of PWM modulation moves t
Reserved. These bits should be set to 00 for normal operation.
