Part Number: AM6548


Please check the operation of UART described in the reference manual "12.1.5.4 UART Functional Description" of am65xx.
Please check "RX time-out" described in "Table 12-610. UART Mode Interrupts".
What is the default setting time for this timeout?
Which register setting can this timeout time be changed?

12.1.5.4.8.1.3.10 Time-Out Counter
Please tell me the register name of "timeout register" described in this chapter.

    Hi Tomitama,

    As described in section 12.1.5.4.8.1.3.10, default UART timeout is '4x the programmed word length + 12 bits'. This default timeout can be changed by configuring the timeout registers 'UART_TIMEOUTL (offset 98h)' and 'UART_TIMEOUTH (offset 9Ch)'. Any non-zero value written to these registers will override the default timeout value. Timeout configured in these registers will be in number of baud clocks.
