FUNCTION
UART B Serial Output. During power-on reset, this pin is pulled
down internally and is defined as PEN48, which provides the
power-on value for CR24 bit 6 (EN48). A 4.7 kΩ resistor is
recommended if intends to pull up.
Data Carrier Detect. An active low signal indicates the modem or
data set has detected a data carrier.
