REFERENCE INFORMATION
LBP
EXAMPLE RPC COMMAND LIST
This is an example stored RPC command list. Note RPC command lists must start
at a RPCPitch boundary in the RPC table but an individual RPC list can extend until the
end of the table. This particular RPC example contains 2 LBP commands and uses 7 bytes
starting at 0x0028 (RPC5 for 0x08 pitch RPC table)
Command1. Writes two data bytes to address 0x10, 0x11 with 2 data bytes supplied by
host
Command2. Reads two data bytes from address 0x12,0x13
