7 NCD_STS In loopback mode, it is equivalent to MCR_REG [3]. R -
6 NRI_STS This bit is the complement of the nRI input. In loopback R -
mode, it is equivalent to MCR_REG [2].
5 NDSR_STS In loopback mode, it is equivalent to MCR_REG [0]. R -
4 NCTS_STS This bit is the complement of the nCTS input. In loopback R -
mode, it is equivalent to MCR_REG [1].
3 DCD_STS Indicates that MCR_REG [3] in loopback changed. R 0
Cleared on a read.
2 RI_STS Indicates that nRI input (or MCR_REG [2] in loopback) R 0
changed state from low to high. Cleared on a read.
1 DSR_STS R 0
0x1: Indicates that MCR_REG [0] in loopback changed
state. Cleared on a read.
0 CTS_STS R 0
0x1: Indicates that nCTS input (or MCR_REG [1] in
loopback) changed state. Cleared on a read.
