Signal List
Table 19-2 presents signal names, functions, and descriptions sorted by pin numbers.
BGA
No entry in this column means that after reset the pin is not reconfigurable and has only one definition.
WSEL, BUSW1, BUSW0, HIZ, and others, refers to function determined by pull-up or pull-down value as seen by
these address pins during reset.
“Port x Cntl Reg” refers to pin function programmed by software writing to GPIO port configuration registers.
MTMOD means that pin function is determined by state of the MTMOD signal.
Requires external protection circuitry to meet USB 1.1 electrical requirements under all conditions (see 12.5.3,
“Recommended USB Protection Circuit”).
