ST16C2552
S
MSR BIT-0:
Indicates that the CTS* input to the ST16C2552 has
changed state since the last time it was read.
MSR BIT-1:
Indicates that the DSR* input to the ST16C2552 has
changed state since the last time it was read.
MSR BIT-2:
Indicates that the RI* input to the ST16C2552 has
changed from a low to a high state.
MSR BIT-3:
Indicates that the CD* input to the ST16C2552 has
changed state since the last time it was read.
MSR BIT-4:
This bit is equivalent to RTS in the MCR during local
loop-back mode. It is the compliment of the CTS*
input.
MSR BIT-5:
This bit is equivalent to DTR in the MCR during local
loop-back mode. It is the compliment of the DSR*
input.
MSR BIT-6:
This bit is equivalent to OP1 in the MCR during local
loop-back mode. It is the compliment of the RI* input.
MSR BIT-7:
This bit is equivalent to OP2 in the MCR during local
loop-back mode. It is the compliment to the CD* input.
Note: Whenever MSR BIT3-0: is set to logic “1”, a
MODEM Status Interrupt is generated.
SCRATCHPAD REGISTER (SR)
ST16C2552 provides a temporary data register to
store 8 bits of information for variable use.
