5.3. M16C/28 Group of MCUs

The M3028x group of 16-bit single-chip, flash microcontrollers (MCU) is part of the M16C/60 series CPU core. The hardware and software manuals for the M16C/28 group of microcontrollers can be found under C:\Renesas\RZB_ZMD16C_ZDK\Docs folder on your PC or from the Start menu (Start > Programs > Renesas > RZB_ZMD16C_ZDK > All Manuals and Documents) after ZDK software installation.

5.4. RZB-ZMD16C-ZDK Board Jumper Configuration

5.4.1. JP1: MCU (U4) Power

JP1 is used to connect the Vcc pins of the M16C/28 MCU to the 3.3V supply of the board. It can be used to measure current/power consumption of the MCU during various modes of operation. For normal operations, JP1 must be shorted.

JP1 is shorted by default.
