The HDLC 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.

These bits should be written with zeros.
A clock glitch was detected by this SCC on the receive clock.
1. RXB event assumes receive buffers are 6 bytes each.
2. The second IDL event occurs after 15 ones are received in a row.
3. The FLG interrupts show the beginning and end of flag reception.
4. The FLG interrupt at the end of the frame may precede the RXF interrupt due to receive FIFO latency.
5. The CD event must be programmed in the port C parallel I/O, not in the SCC itself.
6. F = flag, A = address byte, C = control byte, I = information byte, and CR = CRC byte.
EVENTS
1. TXB event shown assumes all three bytes were put into a single buffer.
2. Example shows one additional opening flag. This is programmable.
3. The CTS event must be programmed in the port C parallel I/O, not in the SCC itself.
