(DC_CYC_CONT: 0x0980).

Generates the SYNC signal debug pulse.
0: Invalid
1: A single debug ping is immediately generated on SYNC0 and SYNC1 pins according to
the setting of bits 2 and 1 in this register.
This bit is self-clearing, and always read as 0.
Specifies the range of near future.
63
0: 2 ns range (1/2 of DC bit width)
31
1: 2 ns range (about 2.1 sec.)
Checks the verification of start time.
0: Invalid. Sync signals are generated if the start time is reached.
1: Sync signals are immediately generated if the start time is out of the near future.
Extends the start time cyclic operation.
0: No extension
1: The start time written in 32 bits is extended to 64 bits.
Enables the SYNC output unit automatically by writing the start time cyclic operation register
(DC_CYC_START_TIME: 0x0990).
0: Disabled
1: Enabled. After the start time was written, 1 is set automatically to bit 0 in this register.
Specifies the use of SYNC1 output.
0: Not used
1: SYNC1 pulse output is generated
Specifies the use of SYNC0 output.
0: Not used
1: SYNC0 pulse output is generated
Specifies the activation of Sync output unit.
0: Deactivated
1: Activated
Note: Write 1 after the start time was written.
