5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
7.7 Modem Status Register (MSR)
This 8-bit register provides information about the current state of the control lines from the
modem, data set, or peripheral device to the processor. It also indicates when a control
input from the modem changes state. Table 15 shows modem status register bit settings
per channel.
[1]
The primary inputs RI, CD, CTS, DSR are all active LOW, but their registered equivalents in the MSR and
MCR (in loopback) registers are active HIGH.
Table 15.
Modem status register bits description
Bit
Symbol
Description
7
MSR[7][1]
CD (active HIGH, logic 1). This bit is the complement of the CD input during
normal mode. During internal loopback mode, it is equivalent to MCR[3].
6
MSR[6][1]
RI (active HIGH, logic 1). This bit is the complement of the RI input during
normal mode. During internal loopback mode, it is equivalent to MCR[2].
5
MSR[5][1]
DSR (active HIGH, logic 1). This bit is the complement of the DSR input
during normal mode. During internal loopback mode, it is equivalent MCR[0].
4
MSR[4][1]
CTS (active HIGH, logic 1). This bit is the complement of the CTS input
during normal mode. During internal loopback mode, it is equivalent to
MCR[1].
3
MSR[3]
CD. Indicates that CD input (or MCR[3] in loopback mode) has changed
state. Cleared on a read.
2
MSR[2]
RI. Indicates that RI input (or MCR[2] in loopback mode) has changed state
from LOW to HIGH. Cleared on a read.
1
MSR[1]
DSR. Indicates that DSR input (or MCR[0] in loopback mode) has changed
state. Cleared on a read.
0
MSR[0]
CTS. Indicates that CTS input (or MCR[1] in loopback mode) has changed
state. Cleared on a read.
