6.12.1.1 UART[x] Primary Dongle and Modem Interface (UART[x]_MOD)
UART1 Primary Dongle and Modem Interface
(UART[1]_MOD)
MSR Address
Type
Reset Value
MSR_UART[x]_MOD is used for primary identification of the dongle interface and also provides the device with a virtual
modem interface. To run legacy software, the modem control bits are set such that the software sees the modem always
ready for data transfer.

Description
Modem 7. This bit directly sets the value of the Ring Indicator (RI) bit of the Modem Status
Register (Bank 0, I/O Offset 06h[6]).
Modem 6. This bit directly sets the value of the Data Set Ready (DSR) bit of the Modem Status
Register (Bank 0, I/O Offset 06h[5]).
Modem 5. This bit directly sets the value of the Data Carrier Detect (DCD) bit of the Modem
Status Register (Bank 0, I/O Offset 06h[7]).
Modem 4. This bit directly sets the value of the Clear to Send (CTS) bit of the Modem Status
Register (Bank 0, I/O Offset 06h[4]).
Primary Dongle Control Signals. This field selects the type of IR Dongle allowing software to
imitate the functionality of a real dongle. These bits are unused in UART mode.
