User manual
4.13 UART1 Scratch Pad Register (U1SCR - 0xE001 001C)
4.14 UART1 Auto-baud Control Register (U1ACR - 0xE001 0020)
Table 409. UART1 Modem Status Register (U1MSR - address 0xE001 0018) bit description
The U1SCR has no effect on the UART1 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 U1SCR has occurred.
Table 410. UART1 Scratch Pad Register (U1SCR - address 0xE001 0014) bit description
The UART1 Auto-baud Control Register (U1ACR) 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.

Data Set Ready State. Complement of input signal DSR. This bit is
connected to U1MCR[0] in modem loopback mode.
Ring Indicator State. Complement of input RI. This bit is connected
to U1MCR[2] in modem loopback mode.
Data Carrier Detect State. Complement of input DCD. This bit is
connected to U1MCR[3] in modem loopback mode.
Rev. 04 — 26 August 2009
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
UART1 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
U1IIR.
