8.7 Modem Control Register (MCR)
The MCR controls the interface with the mode, data set, or peripheral device that is
emulating the modem.

Description
Clock divisor.
IrDA mode enable.
Xon Any.
Enable loopback.

TCR and TLR enable.
RTS
DTR. If GPIO5 or GPIO1 is selected as DTR modem pin through
IOControl register bit 1 or bit 2, the state of DTR pin can be controlled as
below. Writing to IOState bit 5 or bit 1 will not have any effect on the DTR
pin.

logic 0 = divide-by-1 clock input
logic 1 = divide-by-4 clock input
logic 0 = normal UART mode
logic 1 = IrDA mode
logic 0 = disable Xon Any function
logic 1 = enable Xon Any function
logic 0 = normal operating mode
logic 1 = enable local Loopback mode (internal). In this mode the
MCR[1:0] signals are looped back into MSR[4:5] and the TX output is
looped back to the RX input internally.
logic 0 = disable the TCR and TLR register
logic 1 = enable the TCR and TLR register
logic 0 = force RTS output to inactive (HIGH)
logic 1 = force RTS output to active (LOW). In Loopback mode,
controls MSR[4]. If Auto-RTS is enabled, the RTS output is controlled
by hardware flow control.
logic 0 = force DTR output to inactive (HIGH)
logic 1 = force DTR output to active (LOW)
