TOUT1, TOUT2, TOUT3
These are pins for outputs of the NOR gates whose inputs are the comparator output signal
between the SAO output level and the SG level, and each register signal stored by the MCU
interface.
The each output is NOR-gated with the comparator output and the invented signal of CR1-B7 at
TOUT3, the inverted signal of CR1-B6 at TOUT2, and the inverted signal of CR1-B5 at TOUT1.
AVIN, REF1, REF2
These pins are for inputs of two comparators internal to the device. AVIN is connected to each
non-inverting input of comparator1 and comparator2. REF1 is connected to an inverting input
of comparator1 and REF2 is connected to an inverting input of comparator2. The output of each
comparator is connected to the input of ENOR. The interval analog switch SW1 is ON/OFF
controlled by the output which is the logical OR of the ENOR and the CR5-B7 signal. When CR5-
B7 is at "0", the SW1 is turned to OFF if AVIN is within the voltage range of REF1 and REF2 and
the SW1 is turned to ON if AVIN is out of the voltage range of REF1 and REF2.
AIN3+, AIN3-, GSX3, AIN4+, AIN4-, GSX4
These pins are for inputs and outputs of the internal op-amps. Refer to BLOCK DIAGRAM for
the connection.
IO1 to IO14
These pins are for inputs and outputs of the internal analog switch. Refer to BLOCK DIAGRAM
and FUNCTIONAL DESCRIPTION for the connection and the control method.
X1, X2
Crystal oscillator connection pins. X2 is for the clock output pin. When a conventional external
clock is used, X1 should be connected to the ground, X2 should be left open, and the clock should
be input to the MCK pin.
