Signal Descriptions
The signal name, type, and description of each pin in the BCM88335 is listed in Table 15. The symbols shown
under Type indicate pin directions (I/O = bidirectional, I = input, O = output) and the internal pull-up/pull-down
characteristics (PU = weak internal pull-up resistor and PD = weak internal pull-down resistor), if any.
