Signal List
Table 19-1 summarizes the signals, showing default pin functions after system reset. General-purpose port
signals all default to inputs after reset.
Table 19-2 presents the same information sorted by pin number
instead of signal function.
NOTE:
In this manual, the term ‘asserted’ indicates the active signal state; ‘negated’
indicates inactive. Names of active-low signals are given overbars, for
example, INT1 and SDWE.
