Description
This register contains the eight MSBs of the 12-bit t
top four bits of Register 0x4E, which contains the four LSBs of the t
to 5 ns resolution.
Description
These bits contain the four LSBs of the 12-bit t
bits of Register 0x4D, 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.
Description
This register contains the eight MSBs of the 12-bit t
the top four bits of Register 0x50, 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 0x4F, which contains the eight MSBs of the t
5 ns resolution.

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.
Description
This register contains the eight MSBs of the 12-bit t
the top four bits of Register 0x52, 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 0x51, 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 = volt-second balance circuit modulates SR1 and SR2, along with OUTB and OUTD. When this
bit is set, the volt-second balance modulation is applied to the rising edge of SR1 and SR2.
Reserved. This bit should be set to 0 for normal operation.
