SCC Programming Reference
E.1.1.2.3 SCC Data Synchronization Register (DSR). This 16-bit register is located at off-
set $886 (SCC1), $896 (SCC2), and $8A6 (SCC3). The DSR specifies the pattern used for
the frame synchronization procedure. For HDLC, the DSR should be set to $7E7E. The DSR
value after reset is $7E7E.
E.1.1.2.4 HDLC Event Register (SCCE). This 8-bit register is located at offset $888
(SCC1), $898 (SCC2), and $8A8 (SCC3) on D15-D8 of a 16-bit data bus. The SCCE is used
to report events recognized by the HDLC channel. Bits mst be cleared by the user to avoid
missing interrupt events. Bits are cleared by writing ones to the corresponding bit positions
.

0 = No interrupt.
1 = A change in the status of CTS was detected.
0 = No interrupt.
1 = A change in the status of CD was detected.
0 = No interrupt.
1 = A change in the status of the receive data serial line was detected.
0 = No interrupt
1 = An error (CTS lost or underrun) occurred on the transmitter channel.
0 = No interrupt.
1 = A complete frame has been received on the HDLC channel.
0 = No interrupt.
1 = A frame was received and discarded due to lack of buffers.
0 = No interrupt.
1 = A buffer has been transmitted on the HDLC channel (set only if the I bit in the Tx
buffer descriptor is set).
