Sync Control (Register 0x100)
Bits[7:3]—Reserved
Bit 2—Clock Divider Next Sync Only
If the master sync enable bit (Address 0x100, Bit0) and the clock
divider sync enable bit (Address 0x100, Bit 1) are high, Bit 2 allows
the clock divider to sync to the first sync pulse it receives and to
ignore the rest. The clock divider sync enable bit (Address 0x100,
Bit 1) resets after it syncs.
Bit 1—Clock Divider Sync Enable
Bit 1 gates the sync pulse to the clock divider. The sync signal is
enabled when Bit 1 is high and Bit 0 is high. This is continuous
sync mode.
Bit 0—Master Sync Enable
Bit 0 must be high to enable any of the sync functions. If the
sync capability is not used this bit should remain low to
conserve power.
