identify which configuration register is to be accessed. User can then access the addressed
configuration register through the Extended Function Data Register (EFDR, I/O address at 2Fh or 4Fh).
After programming of the configuration register is completed, another specific value (0AAh) should be
written to EFER to leave Extended Function mode to prevent inadvertent accesses to those configuration
registers. User may write a "1" to bit 5 of CR26 (LOCKREG) to prevent configuration registers from
accidental accesses.
6.2.2 Extended Functions Enable Register (EFER)
After a power-on reset, W83L518D/W83L519D
enters the default operation mode. A specific value must
be programmed into the Extended Function Enable Register (EFER) so that configuration registers can
be accessed. On a PC/AT system, its I/O address is 2Eh or 4Eh (as described in previous section).
6.2.3 Extended Function Index Register (EFIR), Extended Function Data Register (EFDR)
After entering Extended Function mode, Extended Function Index Register (EFIR) must be written with
an index value (02h, 07h-FEh) to specify which configuration register is to be accessed through Extended
Function Data Register (EFDR). EFIR is a write-only register at I/O address 2Eh or 4Eh (as described in
section
9
.2.1) on a PC/AT system and EFDR is a read/write register at I/O address 2Fh or 4Fh.
6.3 Configuration Sequence
To program configuration registers, specific configuration sequence must be followed:
(1) Write 83h to EFER twce to enter Extended Function mode.
(2) Select logical device select register by writing 07h to EFIR.
(3) Select logical device by writing a value to EFDR.
(4) Select control/configuration register by writing its index to EFIR.
(5) Access selected control/configuration register through EFDR.
(6) Repeat step 4 ~ 5 as needed.
(7) Leave Extended Function mode by writing AAh to EFER.
Step 2 and step 3 are not necessary for accessing global register (index 00h to 2Fh).
