Setup Example 1: Pulser Mode, Pin Controlled
Program EN_SYNC_PIN_FUNC=1, SYNC pin is enabled for SYSREF requests.
Program SYNC_PIN_FUNC=01, SYNC pin is programmed to accept the SYSREF requests.
Program OUTCH_SYSREF_PLSCNT= xx (max 32), programs the number of SYSREF pulses to be generated.
Program SYSREF_EN_CHxx=1, enables corresponding output channels to generate SYSREF clock pulses.
Apply rising Edge at SYNC pin generates xx number of at the enabled at the enabled channel.
