6. Serial Output Select Function
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.
Mode A (MOD = “L”)
SCK
SOT
SIN
MSB
LSB
Bf Be Bd Bc Bb Ba B9 B8 B7 B6 B5 B4 B3 B2 B1 B0
MSB
LSB
bf be bd bc bb ba b9 b8 b7 b6 b5 b4 b3 b2 b1 b0
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
changing the output mode, make the ENDC inactive or set the RSTX pin level to “L” after switching the
MOD pin.
Mode B (MOD = “H”)
SCK
MSB
LSB
SOT
Bf Be Bd Bc Bb Ba B9 B8 B7 B6 B5 B4 B3 B2 B1 B0
MSB
LSB
SIN
bf be bd bc bb ba b9 b8 b7 b6 b5 b4 b3 b2 b1 b0
Serial data is output at the rising 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
changing the output mode, make the ENDC inactive or set the RSTX pin level to “L” after switching the MOD
pin. The first bit is output when the ENDC signal becomes “H.”
7. Extended Serial Interface
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.
