FUNCTIONAL DESCRIPTION
(Serial Command) Register (Reset status: 0000H)
register contains converter command input channel identification. Accessing this register after releasing from reset status activates converter. Note that this register accepts setting even during conversion. Note also that input command register must take interval least CCLKs after input previous command.

(Standard Conversion) Command
Input command executes conversion specified channel once. Impletion conversion, ENDC signal rises while IRQX signal falls. Clock input after conversion outputs data pin. Upon completion data output, ENDC signal falls while IRQX signal rises. next command STOP NOP, conversion terminated. command input during conversion, command currently being executed cancelled command executed. Example command execution command input during conversion cancels current command executes conversion specified channel. Output data this time 0000H.

Serial Output Select Function
MB88111 select serial data output timing between rising edge falling edge clock signal according setting pin. Mode (MOD "L")
Serial data output falling edge signal. Note: converted data guaranteed switched when ENDC signal active. Before changing output mode, make ENDC inactive RSTX level after switching pin.
Mode (MOD "H")
Serial data output rising edge signal. Note: converted data guaranteed switched when ENDC signal active. Before changing output mode, make ENDC inactive RSTX level after switching pin. first output when ENDC signal becomes "H."
Extended Serial Interface
MB88111 select whether output converted data output data input ESIN controlling CS2X pins. CS2X Connection ESIN converted data
