Signal Descriptions
The signal name, type, and description of each pin in the BCM4356 is listed in Table 21 and Table 22. 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.
