PWM output format

PWM output example

19. CD-ROM outputs; Pin 42: LRSY, pin 43: CK2, pin 44: ROMXA, pin 45: C2F

Although the LC78630E is initially set up to output audio data MSB first from the ROMXA pin in synchronization

with CK2, it can be switched to output CD-ROM data by issuing a CD-ROM XA command. Since this data has not

been processed by the interpolation, previous value hold, muting, and other digital circuits, it is appropriate for input

to a CD-ROM decoder LSI. CK2 is a 2.1168 MHz clock, and data is output on the CK2 falling edge. However, this

clock polarity can be inverted by issuing a CK2 polarity inversion command. C2F is the flag information for the data

in 8-bit units. Note that the CD-ROM XA reset command has the same function as the CONT1 pin (pin 37).

No. 5121-23/33
