4-3-2. Pin Functions

This section describes signals. The input/output states of signals are differentiated by the input (I), outpu
(0), and high impedance (Z). Each signal is grouped by function.

Analog signal pin
AD upper limit reference voltage output. When using
0 Analog
the VRTS output to the VRTA input.
AD upper limit reference voltage input.
I Analog
AD lower limit reference voltage output. When using
0 Analog
the VRBS outuut to the VRBA input.
AD lower limit reference voltage input.
I Analog
Analog data input signal. Analog signal input to the
I Analog
8-bit AD converter. The input to the AD converter is
switched automatically by the analog switch.
0 Analog DACO buffer output signal. DACO buffer output. The
power down mode can be selected.
I Analog DACO buffer upper limit reference voltage input.
I Analog DACO buffer lower limit reference voltage input.
0 Analog
power down mode can be selected.
I Analog DAC 1 buffer upper limit reference voltage input.
I Analog DAC 1 buffer lower limit reference voltage input.
Analog DAC2 buffer output signal. DAC2 buffer output. The
0
power down mode can be selected.
I Analog DAC 1 buffer upper limit reference voltage input.
I Analog DAC2 buffer upper limit reference voltage input.
Analog DAC3 buffer output signal. DAC3 buffer output. The
0
power down mode can be selected.
I Analog DAC2 buffer upper limit reference voltage input.
I Analog
PWM pin
CMOS PWM output signal. &bit PWM output. The output
pulse width can be set any value.
Host interface pin
TTL Host
I
H:Serial, L:Parallel.
I TTL Host serial data/host data read strobe signal input. In
(Internal pull-up) the serial mode, the serial data is input. In the parallel
mode, the data read strobe signal is input.
Function
interface serial/parallel mode selection.
