The UART event register is a memory-mapped register that may be read at any time. A bit
is cleared by writing a one (writing a zero does not affect a bit’s value). More than one bit
may be cleared at a time. All unmasked bits must be cleared before the CP will clear the
internal interrupt request. This register is cleared at reset.

1. The first RX event assumes receive buffers are 6 bytes each.
2. The second IDL event occurs after an all-ones character is received.
3. The second RX event position is programmable based on the MAX_IDL value.
4. The BRKs event occurs after the first break character is received.
5. The CD event must be programmed in the port C parallel I/O, not in the SCC itself.
EVENTS
1. TX event assumes all seven characters were put into a single buffer and CR = 1 in the Tx BD.
2. The CTS event must be programmed in the port C parallel I/O, not in the SCC itself.
