slots (output slots 3 - 12). The CS4610/11 ASDIN
input supports receiving of audio sample data on 6
input sample slots (input slots 3 - 8). The SDO2,
SDO3 serial outputs and the SDIN2 serial input are
not supported in this configuration.
MIDI Port
In the AC’97 controller configuration, the
CS4610/11 provides a bi-directional MIDI inter-
face to allow connection of external MIDI devices.
The CS4610/11 MIDI interface includes 16-byte
FIFOs for the MIDI transmit and receive paths.
Joystick Port
In the AC’97 controller configuration, the
CS4610/11
CS4610/11 joystick port provides four “coordi-
nate” channels and four “button” channels of input
capability. The coordinate channels provide joy-
stick positional information to the host, and the but-
ton
information. The joystick interface is capable of

operating in the traditional “polled” mode, but also
provides a “hardware accelerated” mode of opera-
tion wherein internal counters assist the host with
coordinate position determination. The joystick
schematic is illustrated in Figure 14.
EEPROM Configuration Interface
The CS4610/11 EEPROM configuration interface
allows the connection of an optional external EE-
PROM device to provide power-up configuration
information. The external EEPROM is not required
for proper operation of the CS4610. However, in
some applications power-up configuration settings
other than the CS4610/11 device default values
may be required to support specific operating sys-
tem compatibility requirements (the CS4610/11
default is the CS4610/11 + CS423x configuration).
These default values can be programmed through
BIOS code or by using the external EEPROM.
After a hardware reset, an internal state machine in
the CS4610/11 will automatically detect the pres-
