4-bit Microcontroller
CD Processor
(two input channels)
C1 correction: dual
C2 correction: quadruple
Each of the following pins can be switched by program to a CD processor-dedicated pin:
DSP output: BCK, LRCK, AOUT, DOUT, IPF, SBOK, CLCK, DATA, and SFSY pins.
DAC input: DACin, BCKin, and LRCKin pins.
Note: BCKin and LRCKin are switched as a pair. A CD command is used to specify DAC input settings.
N-channel open-drain I/O ports (for up to 5.5 V): 3 (max)
Clock stop (oscillator stopped)
Hardware wait (only crystal oscillator in operation)
Software wait (CPU in intermittent operation)
