Q Channel 4-bit A-D Converter's digital outputs, which are connected
to the modem data input pins. These data are synchronized at
CHIP 8's rising edge and output. Because they are valid at the falling
edge, the data are latched at the falling edge in the modem.
Power source for a logic circuit ,related to the digital input /output,
connected to an external digital logic such as the modem.
