28.1 Connecting QB-MINI2 to 78K0R/Lx3 microcontrollers
the host machine via an on-chip debug emulator (QB-MINI2).
communication For flash memory programming, 1-line mode is used. 1-line mode or 2-line mode is used for on-chip
debugging. Table 28-1 lists the differences between 1-line mode and 2-line mode.

The 78K0R/Lx3 microcontrollers use the V
Caution The 78K0R/Lx3 microcontrollers have an on-chip debug function, which is provided for development
Notes 1. Connection is not required for communication in 1-line mode but required for communication in 2-line mode.
Remark
1-line mode (single line UART) using the TOOL0 pin or 2-line mode using the TOOL0 and TOOL1 pins is used for serial
2. Connecting the dotted line is not necessary since RXD and TXD are shorted within QB-MIN2. When using
externally, use a resistor of 100 kΩ or more.
and evaluation. Do not use the on-chip debug function in products designated for mass production,
because the guaranteed number of rewritable times of the flash memory may be exceeded when this
function is used, and product reliability therefore cannot be guaranteed. NEC Electronics is not
liable for problems occurring when the on-chip debug function is used.
The FLMD0 pin is recommended to be open for self-programming in on-chip debugging. To pull down
the other flash memory programmer, RXD and TXD may not be shorted within the programmer. In this case,
they must be shorted on the target system.
At this time, perform necessary connections according to Table 2-2 Connection of Unused Pins since
TOOL1 is an unused pin when QB-MINI2 is unconnected.
