edt_intfc_read

Description

A convenience routine, partly for backward compatability, to access the XILINX interface registers.

The register descriptors used be edt_reg_write() can also be used, since edt_intfc_read masks off the

offset.

Syntax

u_char

edt_intfc_read(EdtDev *edt_p, uint_t offset)

Arguments

edt_p

device struct returned from edt_open

offset

integer offset into XILINX interface, or register descriptor

val

unsigned character value to set

Example

u_char rfnct=edt_intfc_read(edt_p, PCD_FUNCT);

Return

void

edt_intfc_write_short

Description

A convenience routine, partly for backward compatability, to access the XILINX interface registers.

The register descriptors used be edt_reg_write() can also be used, since edt_intfc_write_short masks off

the offset.

Syntax

void edt_intfc_write_short(EdtDev *edt_p, uint_t offset, u_short val)

Arguments

edt_p

device struct returned from edt_open

offset

integer offset into XILINX interface, or register descriptor

val

unsigned character value to set

Example

u_short width=1024;

edt_intfc_write_short(edt_p, CAM_WIDTH, width);

Return

void
