3.7.1 Debug Comparison

The Arm SWD 2-wire JTAG port is the main debug and programming interface for MSPM0 devices. This interface is typically used during application development, and during production programming.

Unlike MSPM0 devices, RL78 devices do not have SWD 2-wire JTAG port. RL78 devices use the dedicated flash memory programmer (PG-FP5/6, E1/E2/E2 Lite/E20 on-chip debugging emulator) for debugging and programming. And communication between the programmer and the RL78 microcontroller is established by serial communication using the TOOL0 pin via a dedicated single-line UART of the RL78 microcontroller.
