MSR[5]: DSR Input Status
This input may be used for auto DTR/DSR flow control function, see “Section 5.4, Automatic Hardware
(RTS/CTS or DTR/DSR) Flow Control Operation” on page 34 for complete details. If automatic hardware
flow control is not used, this bit is the compliment of the DSR# input. In the loopback mode, this bit is
equivalent to the DTR# bit in the MCR register. The DSR# input may be used as a general purpose input when
the modem interface is not used.
MSR[6]: RI Input Status
This bit is the compliment of the RI# input. In the loopback mode this bit is equivalent to bit-2 in the MCR
register. The RI# input may be used as a general purpose input when the modem interface is not used.
MSR[7]: CD Input Status
This bit is the compliment of the CD# input. In the loopback mode this bit is equivalent to bit-3 in the MCR
register. The CD# input may be used as a general purpose input
5.8.11
Modem Status Register (MSR) - Write-Only
The upper four bits 4-7 of this register sets the delay in number of bits time for the auto RS485 turn around
from transmit to receive.
MSR [7:4]
When Auto RS485 feature is enabled (FCTR bit-5=1) and RTS# 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# output. This delay is very useful in
long-cable networks. Table 17 shows the selection. The bits are enabled by EFR bit-4.
