SM5844AF
NIPPON PRECISION CIRCUITS—12
FUNCTIONAL DESCRIPTION
Input Data Interface (DI, LRCI, BCKI, IFM1, IFM2)
Attenuator and Deemphasis Selection
The attenuator is set using the microcontroller
interface. When the attenuator is used, deemphasis
settings also need to be set using the microcontroller
interface. The microcontroller interface comprises
MDT, MCK and MLEN, and is used to receive all
input serial data.
When MCOM is HIGH, serial data received on
MDT, MCK and MLEN sets the attenuation data and
control flag data.
When MCOM is LOW, the logic levels on FSI1,
FSI2 and DEEM select the device function.
