E.3.1 Configuration
Serial Ports C and D are brought out as 3-wire RS-232 serial ports on headers J4 and J3 respec-
tively. Jumpers may be installed on header JP7 to use header J3 as a 5-wire RS-232 serial port
with flow control provided by Serial Port C.
Jumpers on headers JP5 connect the MiniCore signals to the RS-232 transceiver. Jumpers may be
installed on header JP7 to use header J3 as a 5-wire RS-232 serial port with flow control provided
by Serial Port C. Note that Serial Port C does not support flow control using serial DMA, so the
following macro must be used with flow control via Serial Port C on the Serial Communication
accessory board.
The jumpers at header JP5 connect the Serial Port D and Serial Port C signals to the RS-232 trans-
ceiver. These jumpers may be removed so that other MiniCore serial port signals may be con-
nected via JP6 to the RS-232 transceiver.
