Interrupt will be generated.
MSR BIT-1:
Logic 0 = No -DSR Change. (normal default condition)
Logic 1 = The -DSR input to the 2550 has changed
state since the last time it was read. A modem Status
Interrupt will be generated.
MSR BIT-2:
Logic 0 = No -RI Change. (normal default condition)
Logic 1 = The -RI input to the 2550 has changed from
a logic 0 to a logic 1. A modem Status Interrupt will be
generated.
MSR BIT-3:
Logic 0 = No -CD Change. (normal default condition)
Logic 1 = Indicates that the -CD input to the has
changed state since the last time it was read. A
modem Status Interrupt will be generated.
MSR BIT-4:
During normal operation, this bit is the compliment of
the -CTS input. During the loop-back mode this bit is
equivalent to MCR bit-1 (-RTS).
MSR BIT-5:
During normal operation, this bit is the compliment of
the -DSR input. During the loop-back mode, this bit is
equivalent to MCR bit-0 (-DTR).
MSR BIT-6:
During normal operation, this bit is the compliment of
the -RI input. Reading this bit in the loop-back mode
produces the state of MCR bit-2 (-OP1)
MSR BIT-7:
During normal operation, this bit is the compliment of
the -CD input. Reading this bit in the loop-back mode
produces the state of MCR bit-3 (-OP2).
Note: Whenever any MSR bit 0-3: is set to logic 1, a
MODEM Status Interrupt will be generated.
Scratchpad Register (SPR)
The ST16C2550 provides a temporary data register to
store 8 bits of user information.
