1.3 Manual Revision History for Revision 2
Table 1-2 lists the changes made in this manual from Revision 1 to Revision 2.
Freescale Semiconductor
Modified signal definitions. Changed all five notes in Table 2-1. All internal
keepers are disabled and do not affect device operation.
Modified signal definitions. Added a note 4, pertaining to GND, at the bottom of
Figure 2-1.
Modified signal definitions. Changed the note at the end of Table 2-3.
Modified signal definitions. In Table 2-8, changed the State During Reset, Stop,
or Wait descriptions for the BR and BB signals.
Modified signal definitions. In Table 2-11, changed the title of the third column to
State During Reset
Changed the State During Reset of all signals to “Ignored input.” Changed the
signal description for PB14.
Pins or signals that are asserted low (made active when pulled to ground) are indicated like
this:
— In text, they have an overbar: for example,
— In code examples, they have a tilde in front of their names. In Example 1-1, line 3
Sets of signals are indicated by the first and last signals in the set, for instance HAD[0–7].
“Input/Output” indicates a bidirectional signal. “Input or Output” indicates a signal that is
exclusively one or the other.
Code examples are displayed in a monospaced font, as shown in Example 1-1.
Hexadecimal values are indicated with a $ preceding the value, as follows: $FFFFFF is the
X memory address for the core interrupt priority register.
The word “reset” is used in four different contexts in this manual:
— the reset signal, written as
— the reset instruction, written as RESET
— the reset operating state, written as Reset
— the reset function, written as reset
