8.7 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 host. It also indicates when a control input
from the modem changes state.
Table 18
shows Modem Status Register bit settings.
[1]
Only available on SC16IS750/SC16IS760.
Remark:
The primary inputs RI, CD, CTS, DSR are all active LOW.

Modem Status Register bits description
Symbol
Description
MSR[7]
CD
[1]
(active HIGH, logical 1). If GPIO6 is selected as CD modem pin
through IOControl register bit 1, the state of CD pin can be read from this
bit. This bit is the complement of the CD input. Reading IOState bit 6 does
not reflect the true state of CD pin.
MSR[6]
RI
[1]
(active HIGH, logical 1). If GPIO7 is selected as RI modem pin through
IOControl register bit 1, the state of RI pin can be read from this bit. This bit
is the complement of the RI input. Reading IOState bit 6 does not reflect the
true state of RI pin.
MSR[5]
DSR
[1]
(active HIGH, logical 1). If GPIO4 is selected as DSR modem pin
through IOControl register bit 1, the state of DSR pin can be read from this
bit. This bit is the complement of the DSR input. Reading IOState bit 4 does
not reflect the true state of DSR pin.
MSR[4]
CTS (active HIGH, logical 1). This bit is the complement of the CTS input.
MSR[3]
CD
[1]
. Indicates that CD input has changed state. Cleared on a read.
MSR[2]
RI
[1]
. Indicates that RI input has changed state from LOW to HIGH.
Cleared on a read.
MSR[1]
DSR
[1]
. Indicates that DSR input has changed state. Cleared on a read.
MSR[0]
CTS. Indicates that CTS input has changed state. Cleared on a read.
