Table 1: Input and Output Descriptions
Symbol rate clock, rising edge active
Asynchronous Master Reset, active high
Input data symbol, 8 bits wide
When high, indicates the data on Data_In is the first symbol in a new information
sequence
When high signifies that the signals at the Data_In and FStart_In ports contain
valid information
Output data symbol, 8 bits wide
When high, indicates the data on Data_Out is the first symbol in a new coded block
When high, signifies that the signals at the Data_Out and FStart_Out ports contain
valid information
Data Bus input from microprocessor
Address Bus from microprocessor
Read Enable for Data Bus
