WPn,val: Set Parameter “n” as “val”
RPn: Return Parameter “n”
SP: Saves Parameter Data to Disk
The WP command changes parameter “n” to a specified value (val). The first time this
command is given, the parameter file is opened and read to memory from the flash disk.
This memory copy is edited using the RP and WP commands. Parameter values range
from 0 to 699 (see Parameters chapter). Table 6-24 shows the communication sequence
for the write parameter command.
