Whenever any MSR bit 0-3 is set to logic 1, a Modem Status Interrupt will be generated.
7.9 Scratchpad Register (SPR)
The SC16C554/554D 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 SC16C554/554D 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 SC16C554/554D 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.
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.
