is written with a 0Dh, this will cause the loader to respond with its banner and prompt using this same
interface. An external microprocessor is assumed to have written and read these values. The RPC loader
implements the same command interface and syntax as the Serial Loader. The only difference is the speed
at which data can be written, and the lack of a baud rate consideration. As bytes are written into the
buffer, they will be acted upon. Handshaking will be used as described in the Parallel I/O section.
The RPC mode requires no super-voltage pulses. The
CS , RD , and WR strobes control the transfer of
data between the DS5001 and the host. This protocol makes the DS5001 ideal for PC based applications,
but any host processor can perform the loading.
