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.
Bits 15–13, 10, 4—Reserved
GLr—Glitch on Rx

EVENTS
15
These bits should be written with zeros.
A clock glitch was detected by this SCC on the receive clock.

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.
RECEIVED BY UART

CHARACTERS
