14.2.7 Control Command Frame Buffer1 Access Register
Address = 6 (read/write)
When CPU writes to this register, data is written to the Control Command Frame Receive Buffer
When CPU reads this register, data is read from the Control Command Frame Transmit Buffer1
14.2.8 Control Command Frame Buffer2 Access Register
Address = 7 (read only)
When CPU reads this register, data is read from the Control Command Frame Transmit Buffer1

1 - Flow Control Off
0 - Flow Control On
When Flow Control On:
In half duplex mode the MAC transmitter applies back pressure for flow control.
In full duplex mode the MAC transmitter sends Flow Control frames when
necessary. The MAC receiver interprets and processes incoming flow control
frames. The Flow Control Frame Received counter is incremented whenever a flow
control is received.
When Flow Control off:
In half duplex mode the MAC Transmitter does not assert flow control by sending
flow control frames or jamming collision.
In full duplex mode the Mac transmitter does not send flow control frames. The
MAC receiver does not interpret or process the flow control frames. The Flow
Control Frame Received counter is not incremented.
