USART Receiver Time-out Register
Name:
Access Type:Read/Write
Reset Value: 0
Offset:
• TO: Time-out Value
When a value is written to this register, a Start Time-out Command is automatically performed.
Time-out duration = TO x 4 x Bit period
USART Transmitter Time-guard Register
Name:
Access Type:Read/Write
Reset Value: 0
Offset:
• TG: Time-guard Value
Time-guard duration = TG x Bit period

Disables the RX Time-out function.
The Time-out counter is loaded with TO when the Start Time-out Command is given or when each new data character is
received (after reception has started).
US_RTOR
0x24
US_TTGR
0x28
Disables the TX Time-guard function.
TXD is inactive high after the transmission of each character for the time-guard duration.
