User manual
10.5.10.1 Auto-baud
10.5.10 UART Auto-baud Control Register
Table 172. UART Scratch Pad Register (SCR - address 0x4000 C01C) bit description
The UART Auto-baud Control Register (ACR) controls the process of measuring the
incoming clock/data rate for the baud rate generation and can be read and written at
user’s discretion.
Table 173. Auto-baud Control Register (ACR - address 0x4000 C020) bit description
The UART auto-baud function can be used to measure the incoming baud-rate based on
the ”AT" protocol (Hayes command). If enabled the auto-baud feature will measure the bit
time of the receive data stream and set the divisor latch registers DLM and DLL
accordingly.

This bit is automatically cleared after auto-baud
completion.
Auto-baud stop (auto-baud is not running).
Auto-baud start (auto-baud is running). Auto-baud
run bit. This bit is automatically cleared after
auto-baud completion.
Auto-baud mode select bit.
Mode 0.
Mode 1.
No restart
Restart in case of time-out (counter restarts at next
UART RX falling edge)
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is
not defined.
End of auto-baud interrupt clear bit (write only
accessible).
Writing a 0 has no impact.
Writing a 1 will clear the corresponding interrupt in the
IIR.
Auto-baud time-out interrupt clear bit (write only
accessible).
Writing a 0 has no impact.
Writing a 1 will clear the corresponding interrupt in the
IIR.
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is
not defined.
