Example:
To program the fifth and sixth locations of the Auxiliary SRAM with $0x01AA the
commands would be:
$0x0000
Cmd
; set ConfigCtrl1 all bits Low
; use default conditions
$0x0118
Cmd
; set ConfigCtrl2 bits 7 and 6 Low
; required by default for these
Reserved bits
; set ConfigCtrl2 bit 4 High
; post-increment addresses on a
read operation
; set ConfigCtrl2 bit 3 High
; enable read/write access to the
Auxiliary SRAM
$0xF300
Cmd
; read SramData LSB register
; read fourth memory location
(LSB). Post-increment pointer.
CmdRd
$0xF3xx ; SramData LSB register data returned ; discard this byte
$0x7002
Cmd
; write SramData LSB register
; write $0x02 to fifth memory
location (LSB)
$0x716A
Cmd
; write SramData MSB register
; write $0x6A to sixth memory
location (MSB)
$0xF000
Cmd
; read SramData LSB register
; read fifth memory location (LSB)
CmdRd
$0xF002 ; SramData LSB register data returned ; check this byte is $0x02
$0xF100
Cmd
; read SramData MSB register
; read sixth memory location (MSB)
CmdRd
$0xF16A ; SramData MSB register data returned ; check this byte is $0x6A
$0x0110
Cmd
; set ConfigCtrl2 bit 3 Low
; disable read/write access to the
Auxiliary SRAM
1.5.6.6 Coefficient Memory
The convention for naming filter coefficients is A1 to An, where n is given by (Filter Length + 1)/2, i.e. for the
15-tap filter, n = 8. This arises from the internal architecture of the filters and the fact that they are all “odd”
and symmetrical. Write or read operations beyond this coefficient number will be reflected about the central
coefficient e.g. the tenth read operation from the 15-tap filter would access coefficient location A6.
There is no practical reason to write or read beyond location n, but the user in any case must avoid write
operations at the (Filter Length + 1) location. This location (A0) location must be zero for the filters to operate
correctly. The global reset (N-RESET pin) establishes this condition when taken Low.

Register Description
This section describes in detail each of the registers and access points addressed by the Command Control
Serial Word.
