CS4614
CrystalClear™ SoundFusion™ PCI Audio Accelerator
The EEPROM device read access sequence is
shown in the Figure 12. The timing follows that of
a random read sequence. The CS4614 first
performs a “dummy” write operation, then
generates a start condition followed by the slave
device address and the byte address of zero. The
CS4614 always begins access at byte address zero
and continues access a byte at a time, using a
sequential read, until all needed bytes in the
EEPROM are read. Since only 7 bytes are needed,
the smallest EEPROM available will suffice.
GENERAL PURPOSE I/O PINS
Many of the CS4614 signal pins are internally mul-
tiplexed to serve different functions depending on
the environment in which the device is being used.
Several of the CS4614 signal pins may be used as
general purpose I/O pins when not required for oth-
er specific functions in a given application.
