The upper four bits [7:4] of this register set the delay in number of bits time for the auto RS-485 turn around
from transmit to receive.
MSR [7:4]: Auto RS485 Turn-Around Delay (requires EFR bit [4]=1)
When Auto RS485 feature is enabled (FCTR bit [5]=1) and RTS#/DTR# output is connected to the enable input
of a RS-485 transceiver. These 4 bits select from 0 to 15 bit-time delay after the end of the last stop-bit of the
last transmitted character. This delay controls when to change the state of RTS#/DTR# output. This delay is
very useful in long-cable networks.

Logic 0 = No change on CD# input (default).
Logic 1 = Indicates that the CD# input has changed state since the last time it was monitored. A modem
status interrupt will be generated if MSR interrupt is enabled (IER bit [3]).
Logic 0 = No change on RI# input (default).
Logic 1 = The RI# input has changed from a LOW to a HIGH, ending of the ringing signal. A modem status
interrupt will be generated if MSR interrupt is enabled (IER bit [3]).
Logic 0 = No change on DSR# input (default).
Logic 1 = The DSR# input has changed state since the last time it was monitored. A modem status interrupt
will be generated if MSR interrupt is enabled (IER bit [3]).
Logic 0 = No change on CTS# input (default).
Logic 1 = The CTS# input has changed state since the last time it was monitored. A modem status interrupt
will be generated if MSR interrupt is enabled (IER bit [3]).
Modem Status Register (MSR) - Write Only
Table 17
shows the selection. The bits are enabled by EFR bit-4.
