Standby mode (active low)
Setting the PWDB pin to the low level sets the LC75010W to standby mode (also know as "power
down mode").
34
PWDB
I
In standby mode, the DSP system clock and the crystal oscillator are stopped and the whole
LC75010W goes to the stopped state. This pin must be held at the high level during normal
operation.
Reset (active low)
35
RSTB
I
A reset is normally applied at power on, after recovering from a temporary power outage, and after
returning from standby mode ("power down mode").
Interrupt (active low) (Software clip input (0/1))
40
INTB
I
Provides feedback control to the DSP to prevent clipping when an overflow occurs in the amplifier
output.

BUSY
O
Outputs the state of the DSP CCB receive buffer.
A low-level output from the BUSY pin indicates that the buffer is empty.
A high-level output indicates that command data is present in the receive buffer.
