Manual Revision History for Revision 2
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, RESET is asserted low.
— In code examples, they have a tilde in front of their names. In Example 1-1, line 3
refers to the SS0 signal (shown as ~SS0).
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.
Example 1-1. Sample Code Listing
BFSET#$0007,X:PCC; Configure:
; MISO0, MOSI0, SCK0 for SPI master
; ~SS0 as PC3 for GPIO
line 1
line 2
line 3
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 RESET
— the reset instruction, written as RESET
— the reset operating state, written as Reset
— the reset function, written as reset
