RL - Read Loop
Command Input
RL ADDR[;B|H|W]
Options
Description
The RL command establishes an infinite loop consisting of a
processor load instruction targeted to the given address and of the
given length (the default data size is word), followed by a branch
instruction back to the load. Hence the address is accessed
repeatedly in rapid succession.
The read loop can only be terminated by an external occurrence,
such as an interrupt (usually an abort), a reset from the RST switch,
or power cycle.
