5. CONTROL PORT INTERFACE
The Control Port is used to load all the internal settings. The operation of the Control Port may be completely asyn-
chronous with the audio sample rate. However, to avoid potential interference problems, the Control Port pins should
remain static if no operation is required.

Memory Address Pointer (MAP)
5.1.1
Memory Address Pointer (MAP) Register Detail
5.1.2
INCR (Auto Map Increment Enable)
Default = ‘0’
0 - Disabled, the MAP will stay constant for successive writes
1 - Enabled, the MAP will auto increment after each byte is written, allowing block reads or writes of suc-
cessive registers
5.1.3
MAP3-0 (Memory Address Pointer)
Default = ‘0000’
5.2
Enabling the Control Port
On the CS4398, the Control Port pins are shared with Stand-Alone configuration pins. To enable the Control
Port, the user must set the CPEN bit. This is done by performing an IC or SPI write. Once the Control Port
is enabled, these pins are dedicated to Control Port functionality.
To prevent audible artifacts, the CPEN bit (see Section 7) should be set prior to the completion of the Stand-
Alone power-up sequence, approximately 218 MCLK cycles. Setting this bit halts the stand-alone power-up
sequence and initializes the Control Port to its default settings. Note, the CPEN bit can be set any time after
RST goes high; however, setting this bit after the stand-alone power-up sequence has completed can cause
audible artifacts.
5.3
Format Selection
The Control Port has two formats: SPI and IC, with the CS4398 operating as a slave device.
If IC operation is desired, AD0/CS should be tied to VLC or GND. If the CS4398 ever detects a high-to-low
transition on AD0/CS after power-up, SPI format will automatically be selected.
5.4
IC Format
In IC Format, SDA is a bidirectional data line. Data is clocked into and out of the part by the clock, SCL,
with a clock-to-data relationship as shown in Figure 14. The receiving device should send an acknowledge
(ACK) after each byte received. There is no CS pin. Pins AD0 and AD1 form the partial chip address and
should be tied to VLC or GND as required. The upper five bits of the 7-bit address field must be 10011.
