FUNCTION
This pin is the mode selection input pin for the hardware and
software mode. For the hardware mode, this pin must be logic
zero input and the SSP_EN pin become the mute input; the
SSPCLK pin and SSPDIN pin become the digital de-emphasis
control input pin. For the software mode, this pin must be logic
one input, and the SSP_EN, SSPCLK, SSPDIN become the
serial setup control input pin to select 4 x 9 bit registers.
This pin is the enable signal for serial setup port(SSP) in the
software mode. If the hardware mode is selected, the pin
becomes the DAC mute input pin when it is the logic zero, the
device is in the mute state; otherwise, it is in the normal
operation.
This pin is the clock input for serial setup port (SSP) in the
software mode. If the hardware mode is selected, this pin and
SSPDIN/DE0 (pin 16) control the selection from the different
digital de-emphasis filter.
This pin is the serial data input for serial setup port(SSP) in the
software mode. If the hardware mode is selected, this pin and
SSPCLK/DE1(pin 17) control the selection from the different
digital de-emphasis filter. It is reserved for the output pin when
it enters the test mode.
