Preface
EP93xx User’s Guide
P
Registers are named using mixed upper and lower case alphanumeric, for example,
SysCfg or PxDDR. Where there are multiple registers with the same names, a lower case
“x” is used as a place holder. For example, in the PxDDR registers, x represents a letter
from A to H, indicating the specific port being discussed
CAUTION:In the Internal Register Map in “Internal Register Map” on page 2-17 some
memory locations are listed as Reserved. These memory locations should not
be used. Reading from these memory locations will yield invalid data. Writing to
these memory locations may cause unpredictable results.
(An example register description is shown below. This description is used for the following
examples.)
A specific bit may be specified in one of three ways:
1. Register name[bit number], for example, SysCfg[29]
2. Register name.bit field[bit number], for example, SysCfg.REV[1]
3. Register name.bit field[bit name], for example, SysCfg.SBOOT
Hexidecimal numbers are referred to as 0x0000_0000.
Binary numbers are referred to as 0000_0000b.
P.5 Register Example
Note: This is only an example. For actual SysCfg register information, see “SysCfg” on page 5-
