XBUF
Crystal oscillator buffer
Function
Pin circuit
• Output buffer for the crystal oscillator circuit
• When XB in the serial data is set to 1, the output buffer operates and
the crystal oscillator signal (a pulse signal) is output.
When XB is 0, XBUF outputs a low level.
After the power-on reset, the output buffer is fixed at the low level.
XOUT
Serial Data I/O Methods
Data is input to and output from the LC72151V using the Sanyo CCB (Computer Control Bus) format, which is the serial
bus format used by SANYO audio ICs. This IC adopts a CCB format with an 8-bit address.
