Hardware description

Parameters:

ResultPtr

: Pointer to register of type

unsigned 1

. Returns 0 for success, 1 for

failure.

Timing:

1 or more clock cycles. It will take more than one clock cycle if you call the macro
directly after the last call to

RC200SmartMediaRead()

or

RC200SmartMediaWrite()

.

Description:

You can only call this macro after a call to

RC200SmartMediaRead()

or

RC200SmartMediaWrite()

.

After a read or write is terminated, this macro ensures that all internal SmartMedia
driver operations are terminated before the next command can be called. Both of
the possible return values from this macro indicate that the SmartMedia driver is in
an idle state. You can then carry out other non-SmartMedia CPLD operations.

Checking for errors during reads and writes

extern macro expr RC200SmartMediaGetError();

You can use this macro to perform a real-time check for errors whilst a read or write operation is in
progress. You can use the macro at any time after the first call to

RC200SmartMediaRead()

or

RC200SmartMediaWrite()

and before you have called

RC200SmartMediaOperationEnd()

. It

will return 1 if there was an error in the previous operation, and return 0 otherwise.

5.16 Ethernet macros

Timing of the Ethernet macros is unpredictable, since the chip has its own CPU, and because of the
unpredictable nature of network communications (for example, a packet could be corrupt).

1. Call

RC200EthernetRun()

in parallel with the rest of the read/write code.

2. Call

RC200EthernetEnable()

.

3. Call

RC200EthernetReadBegin()

or

RC200EthernetWriteBegin()

.

4. Call

RC200EthernetRead()

or

RC200EthernetWrite()

. Data is read or written one

byte at a time.

5. Once the whole packet has been read or written, call

RC200EthernetReadEnd()

or

RC200EthernetWriteEnd()

.

Important considerations:

•

You must call

RC200EthernetReadEnd()

or

RC200EthernetWriteEnd()

at the end

of a read or write, and the driver will not reposnd correctly to further commands until this is
done.

•

If you call either

RC200EthernetReadBegin()

or

RC200EthernetWriteBegin()

and

they return an error, then a read or write operation has not been started, so there is no need
to call the "End" macros.

•

Once you start reading or writing a packet, you must finish it before accessing the network
driver in any other way. For example, it is not permissible to overlap reading and writing of
packets.
