RCIM IV Pin Configuration
1
Unique to the RCIM IV, each of the EXT_INOUT pins can be configured to be either
input or output, as well as terminated or non-terminated.
pin
N
/
[
out
|
in
]/[
non-terminated
|
terminated
]
The flag words (
out
,
in
,
non-terminated
,
terminated
) can be specified using the
first character of the word. These words are not case sensitive.
Examples include:
Default: EXT_INOUT pins 0-5 are outputs, EXT_INOUT pins 6-11 are inputs, and all
pins are non-terminated.
Pins must be configured as inputs before they can be used as sources, and pins must be
configured as outputs before they can be driven by sources.
NOTE
On the RCIM IV you cannot specify a pin as an input source to
driv e the same pin's output. For example, trying to set
"
input0|out0
" is invalid and will result in an “Invalid Argu-
ment” error.
See the “Configuration” section in Chapter 2 or the
rcim(4)
man page for the various
methods available for specifying configuration options.
pin0/out/n
configure EXT_INOUT0 to be output with no termination
pin1/in/t
configure EXT_INOUT1 to be input with termination
pin2/i/terminated
configure EXT_INOUT2 to be input with termination
pin3/o/non-terminated
configure EXT_INOUT3 to be output with no termination
