2.3.1 Read Main Memory (SLE 4432 and SLE 4442)
The command reads out the contents of the main memory (with LSB first) starting at the given byte
address (N = 0…255) up to the end of the memory. After the command entry the IFD has to supply
sufficient clock pulses. The number of clocks is m = (256 – N)
memory is always possible.
