6. Serial Output Select Function

7. Extended Serial Interface

The MB88111 can select the serial data output timing between the rising edge or falling edge of the clock signal

according to the setting of the MOD pin.

The MB88111 can select whether to output A/D converted data or to output data input to the ESIN pin by

controlling the CS1 and CS2X pins.

Note: A/D converted data is not guaranteed if the CS1 or CS2X setting is changed during SCK input.

Mode B (MOD = “H”)

Mode A (MOD = “L”)

Serial data is output at the falling edge of the SCK signal.

Note: A/D converted data is not guaranteed if the MOD pin is switched when the ENDC signal is active. Before
