Whenever any MSR bit 0-3 is set to logic 1, a Modem Status Interrupt will be generated.
7.9 Scratchpad Register (SPR)
The SC16C750 provides a temporary data register to store 8 bits of user information.
7.10 Enhanced Feature Register (EFR)
Enhanced features are enabled or disabled using this register.
1
MSR[1]
DSR
[1]
Logic 0 = No DSR change (normal default condition).
Logic 1 = The DSR input to the SC16C750 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
SC16C750
has changed state since
the last time it was read. A modem Status Interrupt will be generated.

Description
EFR[7]
Automatic CTS flow control.
Logic 0 = Automatic CTS flow control is disabled (normal default
condition).
Logic 1 = Enable Automatic CTS flow control. Transmission will stop
when CTS goes to a logical 1. Transmission will resume when the CTS
pin returns to a logical 0.
EFR[6]
Automatic RTS flow control. Automatic RTS may be used for hardware flow
control by enabling EFR[6]. When Auto-RTS is selected, an interrupt will
be generated when the receive FIFO is filled to the programmed trigger
level and RTS will go to a logic 1 at the next trigger level. RTS will return to
a logic 0 when data is unloaded below the next lower trigger level
(programmed trigger level 1). The state of this register bit changes with the
status of the hardware flow control. RTS functions normally when
hardware flow control is disabled.
0 = Automatic RTS flow control is disabled (normal default condition).
1 = Enable Automatic RTS flow control.
EFR[5-0]
Reserved; set to 0.
