Table 6-10 below describes the function of the jumper headers.
Jumper Settings
Reference Function Open Short Notes
JP7 Speaker
Enable
Headphone Active
Speaker Enabled
Headphones may work to some
extent with jumper fitted – but will
not work optimally
JP9 CAN
terminator
disable
Removes the CAN termination
resistor – useful in some
debugging situations
CAN terminator active
Cut the trace between the pads
to ‘open’ the circuit
JP10 Switch 3
Isolation
Removes Switch 3 from P42/AN2
Circuit
Switch 3 acts on P42/AN2
Cut the trace between the pads
to ‘open the circuit
JP11 Switch 3
Isolation
Removes Switch 2 from P41/AN1
Circuit
Switch 2 acts on P41/AN1
Cut the trace between the pads
to ‘open the circuit
JP12 Switch 3
Isolation
Removes Switch 1 from P40/AN0
Circuit
Switch 1 acts on P40/AN0
Cut the trace between the pads
to ‘open the circuit
JP13 J-Link
Disable
J-Link Lite debugger is active
and works normally
J-Link Lite is disabled with all
output high impedance. This is
useful for running a program
without the debugger or using
the boot mode of the RX62N
-
JP14* Boot Mode
Enable*
TXD1 and TXD2 are not shorted
– normal operation
TXD1 And TXD2 are shorted –
which allows UART Boot Mode
UART Boot Mode also requires
JP13 Short and SW5 configured
for Boot Mode. J5 can then
Boot the RX62N Micro.
JP15* Boot Mode
Enable*
RXD1 and RXD2 are not
shorted – normal operation
RXD1 And RXD2 are shorted –
which allows UART Boot Mode
UART Boot Mode also requires
JP13 Short and SW5 configured
for Boot Mode. J5 can then
Boot the RX62N Micro.
J7 GND N/A N/A Convenient Scope Ground Pins
