J-Link Lite debugger is active 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
TXD1 and TXD2 are not shorted TXD1 And TXD2 are shorted – UART Boot Mode also requires
– normal operation
which allows UART Boot Mode JP13 Short and SW5 configured
for Boot Mode. J5 can then
Boot the RX62N Micro.
RXD1 and RXD2 are not
