SMT335
Throughout this document the term SMT335 will usually be used to refer to both the
SMT335 and the SMT375. It should be clear from the context when a distinction is
being drawn between the two types of module.
Register Descriptions
The format of registers is described using diagrams of the following form:
31–24 23–16 15–8
7–0
OFLAGLEVEL
R,00000000 RW,10000000 R,00000000
R,10000000
The digits at the top of the diagram indicate bit positions within the register and the
central section names bits or bit fields. The bottom row describes what may be done
to the field and its value after reset. Shaded fields are reserved and should only ever
be written with zeroes.
R
Readable by the CPU
W
Writeable by the CPU
RW
Readable and writeable by the CPU
Binary digits indicate the value of the field after reset.
