UART SCCE
A change in the status of the CTS line was detected on the UART channel. The SCC sta-
tus register may be read to determine the current status.
A change in the status of the CD line was detected on the UART channel. The SCC status
register may be read to determine the current status.
A change in the status of the receive serial line was detected on the UART channel. The
SCC status register may be read to determine the current status.
CD
RECEIVED BY UART
EVENTS
1. The first RX event assumes receive buffers are six bytes each.
2. The second IDL event occurs after 9 to 13 ones received in a row.
3. The second RX event position is programmable based on the max_IDL value.
4. The BRK event occurs after the first break character is received.
EVENTS
