Note: The EV kit sets the following MAX3100 register
bits to a fixed logic because the µC firmware relies on
these settings to function properly; a user cannot
change these settings:
•
•
•
•
•
10) On the software GUI, accept the default settings for

FEN = 0 (FIFO Enable. Enables the receive FIFO
when FEN = 0. When FEN = 1, FIFO is disabled.)
TM = 1 (Mask for T bit. IRQ is asserted if TM = 1
and T = 1.)
RM = 1 (Mask for R bit. IRQ is asserted if RM = 1
and R = 1.)
PM = 1 (Mask for Pr bit. IRQ is asserted if PM = 1
and Pr = 1.)
RAM = 1 (Mask for RA/FE bit. IRQ is asserted if
RAM = 1 and RA/FE = 1.)
the PC UART. Click the Select Port drop-down list to
select the COM port that connects to the EV kit.
Press the Open button to open and configure the PC
COM port setting as defined in the PC UART Setting
group box. Check the status bar at the bottom of the
GUI to verify that the port is opened successfully.

Note: Many PCs do not support 230.4kbps baud rate. If
this is the case, select a lower baud rate on the GUI
and open the port. Change the B3–B0 settings on the
EV kit board and press SW1 to configure the MAX3100
accordingly.
11) Click the up or down arrow on the spin box. The PC
The EV kit is only designed to demonstrate the features
of the MAX3100. No robust error checking or flow-
control algorithms are implemented. All data is in raw
binary format without coding and decoding. A user
should connect an oscilloscope to monitor the wave-
forms on the signal lines to better understand the data
transactions.
The software main window includes seven group
boxes, as shown in Figure 1.
