Slot 1 - JP1 Jumper JP1 is used to control a pin of the module hosted on Slot 1. In
Slot 1 - JP11 Jumper JP11 selects whether the ground reference to the module should
Slot 5 - JP2, JP3, JP4 Jumpers JP2, JP3 and JP4 are used to select if the data, clock
Slot 6 - JP5, JP6, JP7, JP8, JP9, JP10 Jumpers JP5, JP6, JP7 can be used to se-
Slot 7 - JP12, JP13, JP14, JP15 Jumpers JP12, JP13, JP14 and JP15 can be used

particular, in position 1-2 a pin of the module is connected to FRCK1 (used for
serial communications with flow control), whereas in position 2-3 it is connected to
the pin RESN (used to handle the input interrupt pin for the TP-UART module).
be given filtered (position 1-2) or not filtered (position 2-3).
and chip select pins of the I2C bus should be connected to the first (position 2-3)
or second (position 1-2) I2C peripheral of the dsPIC. Please note that all the three
jumpers should select the same port (that is, they must be all three in position
1-2 or 2-3).
lectif the data in, data out, and clock of the SPI bus should be connected to the
first (position 2-3) or to the second (1-2) SPI peripheral of the dsPIC (R) DSC.
Please note that all the three jumpers should select the same port (that is, they
must be all three in position 1-2 or 2-3).
Jumpers JP8, JP9, and JP10 control the chip select of the SPI module from either
a general purpose I/O or chip select pin built-in in the microcontroller (see Figure
3.18
to selectif the data in, data out, clock and chip select of the Ethernet bus should
be connected to the first (position 2-3) or to the second (1-2) SPI peripheral of the
dsPIC (R) DSC. Please note that all the four jumpers should select the same port
(that is, they must be all four in position 1-2 or 2-3).
