PXD10RM Datasheet, PDF (35/1332 Pages) Freescale Semiconductor, Inc – PXD10 Microcontroller

This document uses the following conventions for the register reset values in register figures:
—
Bit value is undefined at reset.
U
Bit value is unchanged by reset. Previous value preserved during reset.
[signal_name]
Reset value is determined by the polarity of the indicated signal.
The following descriptions are used in register bit field description tables:
R0
W
Indicates a reserved bit field in a memory-mapped register. These bits are always read
as 0.
R1
W
Indicates a reserved bit field in a memory-mapped register. These bits are always read
as 1.
R FIELDNAME
W
Indicates a read/write bit in a memory-mapped register.
R FIELDNAME
W
Indicates a read-only bit field in a memory-mapped register.
R
W FIELDNAME
Indicates a write-only bit field in a memory-mapped register.
R FIELDNAME
W
w1c
Write 1 to clear: indicates that writing a 1 to this bit field clears it.
R
0
W FIELDNAME
Indicates a self-clearing bit.
