5 V, 2.2 V and 2.5 V dual UART, 5 Mbit/s (max.), with 64-byte FIFOs
7.6 Modem Control Register (MCR)
The MCR controls the interface with the mode, data set, or peripheral device that is
emulating the modem.
Table 14
shows modem control register bit settings.
Table 14.
Bit

[1]
MCR[7:5] can only be modified when EFR[4] is set, i.e., EFR[4] is a write enable.
Modem Control Register bits description
Symbol
Description
MCR[7]
[1]
Clock select.
logic 0 = divide-by-1 clock input
logic 1 = divide-by-4 clock input
MCR[6]
[1]
TCR and TLR enable.
logic 0 = no action
logic 1 = enable access to the TCR and TLR registers
MCR[5]
[1]
Xon Any.
logic 0 = disable Xon Any function
logic 1 = enable Xon Any function
MCR[4]
Enable loopback.
logic 0 = normal operating mode.
logic 1 = enable local Loopback mode (internal). In this mode the MCR[3:0]
signals are looped back into MSR[7:4] and the TXn output is looped back to
the RXn input internally.
MCR[3]
IRQ enable OP.
logic 0 = forces INTA, INTB outputs to the 3-state mode and OP output to
HIGH state
logic 1 = forces the INTA-INTB outputs to the active state and OP output to
LOW state. In Loopback mode, controls MSR[7].
MCR[2]
FIFO Ready enable.
logic 0 = disable the FIFO Rdy register
logic 1 = enable the FIFO Rdy register. In Loopback mode, controls MSR[6].
MCR[1]
RTS
logic 0 = force RTSn output to inactive (HIGH)
logic 1 = force RTSn output to active (LOW). In loopback mode, controls
MSR[4]. If auto-RTS is enabled, the RTSn output is controlled by hardware
flow control.
MCR[0]
DTR
logic 0 = force DTRn output to inactive (HIGH)
logic 1 = force DTRn output to active (LOW). In Loopback mode, controls
MSR[5].
