Receive responds to a basic Receive request from the master. In Return Byte Count,

enter the number of bytes a Receive request will respond with, then enter the data to

be returned in the data array. The Basic page limits you to eight bytes of returned data.

Write simply displays the byte count and data written by the master.

Read responds to a basic Read request by the master. In Return Byte Count, enter the

number of bytes a Read request will respond with, then enter the data to be returned

in the data array. The Basic page limits you to eight bytes of returned data.

Byte Count will display the number of bytes between the slave read address and the

slave write address. Data will display the data between the slave read address and the

slave write address.
