Digital input/output control part (dio2_top)
Controls the bi-directional buffer when a differential input/output circuit board is connected. It generates the 1-bit bidirectional
buffer digital input signal, digital output signal, and input/output direction signal that controls the digital input/output.
The digital input signal and digital output signal have the same functions as the digital input control part and digital output
control part. The input/output direction signal that controls digital input/output selects and outputs the signal in the user circuit
block or the register part.

■Digital input/output control circuit
According to the setting values of output signal/input output direction signal selection (B0) to output signal/input output direction
signal selection (B2), and output signal/input output direction signal selection (E0) to output signal/input output direction signal
selection (E2), this function selects and outputs the user circuit block digital output or the register part output.
Also, the external reset ON/OFF setting controls the input/output of the differential input/output circuit when the internal operation
start/stop is Stop(0).
• When the external reset ON/OFF setting is set to ON: Outputs with 0 fixed. (The differential input/output circuit is fixed to the
input direction.)
• When the external reset ON/OFF setting is set to OFF: Outputs the signal selected by the setting value of the output signal or I/
O direction signal selection (B0 to E2).
