Whenever any MSR bit 0-3 is set to logic 1, a Modem Status Interrupt will be generated.
7.9 Scratchpad Register (SPR)
The SC16C2550B provides a temporary data register to store 8 bits of user
information.

MSR[1]
DSR
[1]
Logic 0 = No DSR change (normal default condition).
Logic 1 = The DSR input to the SC16C2550B has changed state
since the last time it was read. A modem Status Interrupt will be
generated.
CTS
[1]
Logic 0 = No CTS change (normal default condition).
Logic 1 = The CTS input to the SC16C2550B has changed state
since the last time it was read. A modem Status Interrupt will be
generated.
