User manual
4.10 UARTn Auto-baud Control Register (U0ACR - 0xE000 C020, U2ACR -
4.9 UARTn Scratch Pad Register (U0SCR - 0xE000 C01C, U2SCR -
0xE007 801C U3SCR - 0xE007 C01C)
The UnSCR has no effect on the UARTn operation. This register can be written and/or
read at user’s discretion. There is no provision in the interrupt interface that would indicate
to the host that a read or write of the UnSCR has occurred.
Table 388. UARTn Scratch Pad Register (U0SCR - address 0xE000 C01C,
0xE007 8020, U3ACR - 0xE007 C020)
The UARTn Auto-baud Control Register (UnACR) 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.

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
UART0 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 1 will clear the corresponding
interrupt in the UnIIR. Writing a 0 has no impact.
Auto-baud time-out interrupt clear bit (write only
accessible). Writing a 1 will clear the corresponding
interrupt in the UnIIR. Writing a 0 has no impact.
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
