NIPPON PRECISION CIRCUITS—14
Microcontroller Interface
For microcontroller setting (when P/M is HIGH), the
microcontroller interface consisting of MDT (data),
MCK (clock) and MLEN (latch enable) can be used.
Data from the microcontroller is input to the input-
stage shift registers at the rise of MCK. Changes in
MDT should be performed at the rise of MCK.
Serial data in the shift registers is latched in parallel
to the flag registers at the rise of MLEN.
Two flag registers are available, divided into the
attenuation factor and mode flag by the D7 data.
A0 to A6: Attenuation factor (A6: MSB)
FDEM: Deemphasis ON/OFF (ON when 1)
FBB1: Bass boost setting switch flag 1
FBB2: Bass boost setting switch flag 2
MONO: Stereo/mono setting (Mono when 1)
CSEL: Mono output channel selection
(Right channel when 1)
