Dual UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
8.9 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 21 shows Modem Status Register bit settings per
channel.
Remark: The primary inputs RI, CD, CTS, DSR are all active LOW.
8.10 Scratchpad Register (SPR)
The SC16IS752/SC16IS762 provides a temporary data register to store 8 bits of user
information.
Table 21.
Modem Status Register bits description
Bit
Symbol
Description
7
MSR[7]
CD (active HIGH, logical 1). If GPIO6 or GPIO2 is selected as CD
modem pin through IOControl register bit 1 or bit 2, the state of CD pin
can be read from this bit. This bit is the complement of the CD input.
Reading IOState bit 6 or bit 2 does not reflect the true state of CD pin.
6
MSR[6]
RI (active HIGH, logical 1). If GPIO7 or GPIO3 is selected as RI modem
pin through IOControl register bit 1 or bit 2, the state of RI pin can be
read from this bit. This bit is the complement of the RI input. Reading
IOState bit 7 or bit 3 does not reflect the true state of RI pin.
5
MSR[5]
DSR (active HIGH, logical 1). If GPIO4 or GPIO0 is selected as DSR
modem pin through IOControl register bit 1 or bit 2, the state of DSR pin
can be read from this bit. This bit is the complement of the DSR input.
Reading IOState bit 4 or bit 0 does not reflect the true state of DSR pin.
4
MSR[4]
CTS (active HIGH, logical 1). This bit is the complement of the CTS
input.
3MSR[3]
CD. Indicates that CD input has changed state. Cleared on a read.
2MSR[2]
RI. Indicates that RI input has changed state from LOW to HIGH.
Cleared on a read.
1MSR[1]
DSR. Indicates that DSR input has changed state. Cleared on a read.
0MSR[0]
CTS. Indicates that CTS input has changed state. Cleared on a read.
