OUTPIN_SYNC 0x22 (34) Type: Read/Write Value at RESET: 0x0000
The OUTPIN_SYNC register determines the synchronization source for the SYNC_OUT pin. Because the
SYNC_OUT pin is often used to synchronize hardware that follows the GC1115, OUTPIN_SYNC is normally set
to SYNC_A or SYNC_B.

SIG_GEN_SYNC 0x23 (35) Type: Read/Write Value at RESET: 0x0000
The SIG_GEN_SYNC register determines the synchronization source for the GC1115’s internal signal generator.
After the SIG_GEN_CTL, SIG_GEN_BASE, and SIG_GEN_INC registers have been initialized, a
SIG_GEN_SYNC trigger starts the signal generator. It is convenient for the microprocessor or DSP to use
SW_TRIGGER as the SIG_GEN_SYNC source. As soon as the SIG_GEN_CTL, SIG_GEN_BASE, and
SIG_GEN_INC registers have been initialized, the microprocessor or DSP can then simply write a 0x400 to
SW_TRIGGER, causing a sync event that only affects the SIG_GEN_SYNC functional block.
