Frame Length 3 to 0 

00xx: Data length is 8 bits and frame length is 8 bits. 

0100: Data length is 8 bits and frame length is 16 bits. 

0101: Data length is 8 bits and frame length is 32 bits. 

0110: Data length is 8 bits and frame length is 64 bits. 

0111: Data length is 8 bits and frame length is 128 bits.

Output when Transmission is Invalid* 

0: High output (1 output) when invalid 

1: High-impedance state when invalid 

Note: Invalid means when disabled, and when a slot that 

is not assigned as transmit data or control data is 
being output.
