LC7874E
With the LC7860K/63 interface, SBCK is transmitted when SFSY is confirmed to be low approximately 2.2 μs after a
falling edge of SFSY is detected. With other interfaces, SBCK is transmitted when SFSY is confirmed to be high and
SBSY to be low approximately 2.2 μs after a rising edge of SFSY is detected.
(1) LC7860 interface [DSP pin names shown in parentheses]
(2) LC7861N/67 interface [DSP pin names shown in parentheses]
(3) LC78681/62X/63X Series interface
Same as (2), except that the SBCK polarity is shifted inversely (shifted on rise of SBCK).
3. DRAM interface
Interface pins: A0 to A7, DB0 to DB3, RAS, CAS, WE, OE

4-bit DRAM is connected externally. The interface pins are set to high impedance by driving the CE1 pin
high. MPEG DRAM sharing is possible.
4. CD graphic monitor pin: CDGM
CDGM goes high once the LC7874E accepts any CD-G instruction. In the power-on state, once CDGM goes high it
remains high. It can be driven low by driving the INIT pin low or transferring an INIT command from the
microcontroller.
