HIGH PERFORMANCE DUART WITH 64-BYTE FIFO
MCR[2]: OP1# / FIFO Rdy Enable
OP1# is not available as an output pin on the M752. But it is available for use during Internal Loopback Mode
(MCR[4] = 1). In the Internal Loopback Mode, this bit is used to write the state of the modem RI# interface
signal.
This bit is also used to select between the SPR, TLR and FIFO Rdy registers. All of these registers are
accessible at address offset 0x7 when LCR≠0xBF. However, LCR = 0xBF is required to access EFR.

MCR[3]: OP2# Output / INT Output Enable
This bit enables or disables the operation of INT, interrupt output. If INT output is not used, OP2# can be used
as a general purpose output.
Logic 0 = INT (A-B) outputs disabled (three state mode) and OP2# output set HIGH(default).
Logic 1 = INT (A-B) outputs enabled (active mode) and OP2# output set LOW.
MCR[4]: Internal Loopback Enable
Logic 0 = Disable loopback mode (default).
Logic 1 = Enable local loopback mode, see loopback section and Figure 13.
MCR[5]: Xon-Any Enable (requires EFR bit-4=1 to write to this bit)
Logic 0 = Disable Xon-Any function (default).
Logic 1 = Enable Xon-Any function. In this mode, any RX character received will resume transmit operation.
The RX character will be loaded into the RX FIFO, unless the RX character is an Xon or Xoff character and
the M752 is programmed to use the Xon/Xoff flow control.
MCR[6]: TCR and TLR Enable (requires EFR bit-4=1 to write to this bit)
This bit enables the TCR and TLR registers at address offset 0x6 and 0x7, respectively. See Table 12 above
for the correct register setting to access the TLR register. See Table 13 below for the setting to access the
TCR register.
Logic 0 = Reserved (default).
Logic 1 = Enable access to the TCR and TLR registers.
