Whenever any MSR bit 0-3 is set to logic 1, a Modem Status Interrupt will be generated.
7.9 Scratchpad Register (SPR)
The SC16C654/654D 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.
Bits 0 through 4 provide single or dual character software flow control selection.
When the Xon1 and Xon2 and/or Xoff1 and Xoff2 modes are selected, the double
8-bit words are concatenated into two sequential numbers.
1
MSR[1]
DSR
[1]
Logic 0 = No DSR change (normal default condition).
Logic 1 = The DSR input to the SC16C654/654D 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 SC16C654/654D has changed state
since the last time it was read. A Modem Status Interrupt will be
generated.

Description
EFR[7]
Auto CTS. 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]
Auto RTS. 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.
Logic 0 = Automatic RTS flow control is disabled (normal default
condition).
Logic 1 = Enable Automatic RTS flow control.
