1. EMC
This module is designed to operate from within an enclosed host system, which is
built to provide EMC shielding. Operation within the EU EMC guidelines is not
guaranteed unless it is installed within an adequate host system.
This module is protected from damage by fast voltage transients originating from
outside the host system, which may be introduced through the output cables.
Short-circuiting any output to ground does not cause the host PC system to lock up
or reboot.
2. Power
This module must be fixed to a TIM40 compliant carrier board. Additionally, a 3v3
power source must be provided to the fixings. This is normally achieved by means of
a power source provided directly through conducting pillars on the carrier board. On-
board dc-dc converters provide power for the analog components on this module.
All of the analog circuitry is shielded on the top and bottom of the module using
custom RFI shielding cans.
3. Notational convention
The format of registers is described using a diagram of the following form:
31–20 19–17 16–8 7–0
LED[4:2]
W,000000000000 W,100 W,000000000 W,10000000
Figure 1: Register Format
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
