2.2 CODEC Control Tab
The “CODEC Control” tab provides high-level control of many CS4244 register settings. Status text detailing
the CODEC’s specific configuration is shown as part of certain controls. The text shown depends on the
setting of the associated control. Note that the Update button (described below) must be pressed to show
the current status of the CS4244 registers represented in this tab. A description of each control group is
outlined below. See the CS4244 data sheet for complete register descriptions.
Serial Port Configuration—Configures the CS4244’s serial port and provides controls for related interrupts.
Note that changes to these settings during normal operation may violate the device’s recommended power
up or power down sequence; refer to the CS4244 data sheet for more information.
Power—Provides a means to power up or power down each ADC and DAC of the CS4244. Note that it is
the user’s responsibility to ensure that the “VA Selection” control correctly reflects the VA supply level.
Miscellaneous Controls—Configures interrupt behavior and various ADC options, as well as selects the
CS4244’s I²C address.
TDM Options—Configures the CS4244’s serial port when operating in the TDM interface format. Note that
the CS4244 cannot operate in TDM mode using the CDB4244 alone; instead the CS4244 must be con-
trolled externally to exercise the device’s TDM capabilities. Refer to
Section 1.8 on page 5 for more infor-
mation on how to release the CS4244 from the board’s command and control it with an external device.
Update—Reads all registers in the CS4244 and reflects the current values in the GUI.
Reset—Resets the CS4244.
