The above program is an example to change the trailing code to H03. The
new trailing code H0003 is written into SW068 in the sub-program 1 (initial
program).
(2) Data receive operation
When a message is received, it is stored in the receive buffer. The receive
buffer is a temporally memory, which has 512 bytes capacity. The expanded
transfer (XFER) instruction is used to read the message from the receive buffer
and to store it into user registers.
