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
