Defines the source of the 8 KHz reference signal on the MC1 bus.

DWORD swiConfig8KRefClock ( SWIHD swihd,
DWORD source,
DWORD network)

swihd Handle returned by swiOpenSwitch.

source Specifies where the 8 KHz reference signal originates. Refer to the Details section for acceptable values.

network Device source of the 8KREF signal. Refer to the Details section for acceptable values.

• SUCCESS
• CTAERR_DRIVER_ERROR
  The underlying driver retrieved an unrecognized error. Call swiGetLastError to retrieve the MVIP device error code.
• CTAERR_INVALID_HANDLE
  swihd is not a valid switch handle.
• SWIERR_INVALID_CLOCK_PARM
  Value of source or network is invalid. Call swiGetLastError to retrieve the MVIP device error code.

• None.

This function defines the source of the 8 KHz reference signal on the MC1 bus.

Acceptable values for source are:

MVIP95_SOURCE_DISABLE
MVIP95_SOURCE_INTERNAL
MVIP95_SOURCE_SEC8K
MVIP95_SOURCE_MVIP
MVIP95_SOURCE_NETWORK

Acceptable values for network are 1 to n where n is the number of devices capable of being a source for 8KREF.

Refer to Chapter 5 for more information about configuring clocks. Refer to the MC1 Installation and Developer's Manual for more information about MC1.

If CTAERR_DRIVER_ERROR is returned, call swiGetLastError to retrieve the MVIP device error code.
