MAX9880A Evaluation Kit
The MAX9880A EV kit software is divided into three tabs:
Analog Audio, Digital Audio, and Control Registers.
The analog and digital tabs are image-based tabs, pro-
viding a visualization of the MAX9880A’s (U1) configura-
tion and an interpretation of the register organization.
The control tab provides a map of the device registers,
as well as configuration control of each register bit.
The software also includes a Status group box (see the
Status Register section), five command buttons, a menu
bar, and a status bar. The status bar is used to report EV
kit connectivity, the interface mode, the device’s address

Reads all device registers and updates all three tabs to reflect the state of the device registers.
Writes all the hex values (0x??) shown on the Control Registers tab to the associated register on
the U1 device.
Resets the device to its power-on-reset (POR) state.
Attempts to establish a connection to the EV kit. First establishing a connection with the EV kit’s
on-board microcontroller (MAXQ2000) and then with the device.
Toggles the device SHDN bit. When enabled, the button’s image turns blue.
Loads/saves a .ax27 configuration file (see the Save/Load Settings section).
Closes the software.
Enables the CS8427 register tab, providing access to the digital audio transceiver’s (U11)
registers (refer to the Cirrus Logic CS8427 data sheet for details).
Enables continuous device detection.
Enables polling of the Status register (0x00).
Set/clear the device’s interrupt enables.

the menu bar items are discussed in the Menu Bar sec-
tion.
The controls for the device registers are discussed in
subsequent sections, which have been organized in
the same manner as the register descriptions in the
MAX9880A IC data sheet. As such, when evaluating the
EV kit hardware and software, both the IC data sheet and
the EV kit data sheet should be referenced.
The software’s menu bar provides five drop-down menus:
