the other. The difference between the pointers become the actual FBS (free buffer size). Data is recorded
from Cx_TW_PR according to such size, and when the data recording is complete, Cx_TW_PR is increased
according to the size of the recorded data and executes the send command.

Above diagram illustrates the change in Cx_TW_PR and Cx_TA_PR when actual data transmission is made
after 2KB of transmission memory is set at CH0.
TCP Reception Memory Size Set-up
Receiving memory of W3100A has the same structure of the transmission memory and operated in same
method.
The memory is comprised of 8KB in total, and the size can be assigned for each channel through RMSR (Rx
data Memory Size register). An example of RMSR and each memory size is illustrated in the diagram
below.
When the memory size from channel 0 exceeds 8KB, all ensuing memory is ignored.
