EDT_OCX_SKIP_LOAD

#define EDT_OCX_SKIP_LOAD   0x400

Disable loading correct bitfile; fail instead.

EDT_OCX_FULL_INIT

#define EDT_OCX_FULL_INIT   0x800

Initialize baseboard as well as mezzanine.

EDT_OCX_LOOPBACK

#define EDT_OCX_LOOPBACK   0x2000

Enable loop back through LIU.

EDT_OCX_REMOTE_LPBK

#define EDT_OCX_REMOTE_LPBK   0x10000

Enable remote loopback from LIU.

EDT_OCX_SCRAMBLE

#define EDT_OCX_SCRAMBLE   0x1000

Enable TX scrambler.

EDT_OCX_INVERT

#define EDT_OCX_INVERT   0x4000

Invert data when checking.

EDT_OCX_SET_DEMUX

#define EDT_OCX_SET_DEMUX   0x8000

Set the demux array.

EDT_OCX_TAGGED_DATA

#define EDT_OCX_TAGGED_DATA   0x80000

Turn on OC192 data tagging.

EDT_OCX_ENABLE_COUNT_DATA

#define EDT_OCX_ENABLE_COUNT_DATA   0x100000

Enable a 32 bit counter data instead of input data, for debug.

EDT_OCX_FREERUN_COUNT_DATA

#define EDT_OCX_FREERUN_COUNT_DATA   0x200000

Enable the 32 bit counter to free run to get latency and bandwidth info.

Function Documentation

edt_reg_set_bitmask()

int edt_reg_set_bitmask	(	EdtDev	edt_p,
		u_int	reg,
		u_int	mask,
		int	state
	)

Set or clear mask bits in register reg .

Parameters

edt_p	The open EDT device handle.
reg	Descriptor of register to modify.
mask	If a bit is set to one in this mask, that bit will be modified. Bits set to zero will not be modified.
state	Enable (1) to set (OR with mask) mask bits in the register. Disable (0) to clear (AND with ~mask) the mask bits in the register.

Returns

The new value of the register.

Here is the call graph for this function:

edt_wait_register_bits_low()

int edt_wait_register_bits_low	(	EdtDev	edt_p,
		u_int	reg,
		u_int	mask,
		int	timeout
	)

Wait until the mask bits in reg have cleared to zero.

Parameters

edt_p	The open EDT device handle.
reg	Descriptor of register to read with edt_reg_read().
mask	Bits set to one in this mask will be checked.
timeout	Timeout, in millseconds, to wait for all bits to clear to zero. Pass zero to wait indefinitely.

Returns

0 if all masked register bits were zero in under timeout ms. Non-zero if timeout occurred.

Here is the call graph for this function:

edt_wait_register_bits_low_timer()

int edt_wait_register_bits_low_timer	(	EdtDev	edt_p,
		u_int	reg,
		u_int	mask,
		int	timeout
	)

Wait until the mask bits in reg have cleared to zero.

Parameters

edt_p	The open EDT device handle.
reg	Descriptor of register to read with edt_reg_read().
mask	Bits set to one in this mask will be checked.
timeout	Timeout, in millseconds, to wait for all bits to clear to zero. Pass zero to wait indefinitely.

Returns

Time, in millseconds, spent waiting for bits to clear.

Here is the call graph for this function:

edt_wait_register_bits_high()

int edt_wait_register_bits_high	(	EdtDev	edt_p,
