  • Page 17: Mcu Headers

    The MCU headers are provided for by two sets of through holes (J1 and J2), each allowing for headers for a total of 40 pins. The pin headers have a pitch of 2.54 mm. The RL78/G14 is connected to the through holes for the headers in the same order of pin numbers, i.e.

  • Page 18: Emulator Reset Header

    The emulator is placed in the forced reset state by short-circuiting the emulator reset header (EJ1). This allows stand-alone operation of the RL78/G14 independently of control by the IDE while the IDE is applying a forcible reset. Figure 5-3 shows the position of the emulator reset header (only through-holes are provided; an actual header component is not mounted).

  • Page 19: Power-Supply Selection Header

    Power-Supply Selection Header The operating voltage of the RL78/G14 can be changed to VBUS (5 V) or 3.3 V with the use of this header (J4). To change the operating voltage, mount a header (J4) and remove the pattern for cutting (SS11). Figure 5-4 shows the connection of the header for VBUS output, and Figure 5-5 shows the connection of the header for 3.3-V output.
