Hardware description

Parameters:

None.

Timing:

Dependant on clock rate. Minimum: 4 clock cycles.

Description:

Sets the reset pin low for at least 100ns, forcing the Ethernet chip to reset.

You need to call

RC200EthernetEnable()

after you reset the device.

5.16.6 Reading a packet

Starting the read process

extern macro proc RC200EthernetReadBegin (

StatusPtr

,

DestinationPtr

,

SourcePtr

,

DataByteCountPtr

,

ResultPtr

);

Parameters:

StatusPtr

: Pointer to data of type

unsigned 16

. Returns the status data from

the received packet.

DestinationPtr

: Pointer to data of type

unsigned 48

. Returns the destination

MAC address from the received packet.

SourcePtr

: Pointer to data of type

unsigned 48

. Returns the source MAC

address from the received packet.

DataByteCountPtr

: Pointer to data of type

unsigned 11

. Returns the number

of data bytes in the received packet.

ResultPtr

: Pointer to data of type

unsigned 1

. Returns 1 if the macro has

timed out while waiting for a packet (failure) or 0 (success).

Timing:

At least 70 clock cycles. There is a timeout of 0.5s if no packet is received.

Description:

Checks if a packet is waiting to be read, and if it is, starts the read process and
returns destination, source, status and byte count from the packet header.

If it times out while waiting for a packet,

ResultPtr

is returned as '1', otherwise it

is returned as '0'. In this case, no further packet read commands should be issued.

Reading a byte of data from a packet

extern macro proc RC200EthernetRead (

DataPtr

,

ResultPtr

);

Parameters:

DataPtr

: Pointer to data of type

unsigned 8

. Returns a byte of data from the

received packet.

ResultPtr

: Pointer to data of type

unsigned 1

. Returns 1 (failure) or 0

(success).

Timing:

2 or 7 clock cycles alternately, and up to 12 clock cycles for the final read.

The macro reads a byte at a time, but Ethernet accesses are 16-bit. When a byte
of data is already buffered on the chip the read only takes 2 clock cycles.

Timing may differ if other accesses to the chip precede a read operation.

Description:

Reads a single data byte from the packet currently being read.

Returns

ResultPtr

= 1 to indicate an error if there is no data remaining in the

packet or if there is no read in progress.

Data is read a byte at a time, but communications with the Ethernet chip are 16-bit,
so a byte is buffered in the Ethernet data structure, until there are 16 bits to read.

You must call

RC200EthernetReadBegin()

before this macro.
