Signal Descriptions
The signal name, type, and description of each pin in the BCM4390 are listed in Table 9. The symbol listed in
the Type column indicates the pin direction (I/O = bidirectional, I = input, O = output) and the internal pull-up/
pull-down characteristics, if any (PU = weak internal pull-up resistor and PD = weak internal pull-down resistor).
