PMX command set (API)

A4354-2.2 HBM: public
PMX
The outputs are available even if no PX878 is plugged in.
In that case they are virtual. They can be set, read back,
but are not electrically present.
p2 defines the selected bits which corresponding output
is set or cleared with p1. The outputs which correspond­
ing bits are 0 in p2 are not affected.
The bits 16 … 31 are always virtual !
Example: ROP2, 32770(x)
0(y)
Output 8 (bit 15) of the second PX878 is cleared and
output 2 (bit 1) of the first PX878 is set (the output count
starts with 1).
These two bits are the only ones selected with p2. All the
other outputs are unchanged.
Notice
The outputs of the PMX device are defined by the
settings stored in the (sub­) parameter sets that can also
be enabled. This command changes the settings of the
selected outputs of the sub­parameter sets being used,
so that the output switches to the desired status. If a
parameter set is connected, an earlier ROP command is
overwritten. So you must be careful what you do!
