Product configuration
*1 Operates in the medium-speed mode (instruction clock: f (XIN)/12) immediately after reset
termination.
*2 Ports P20 and P21 are used with both SEG16 and SEG17, and function as output ports when the
segment output is selected.
*3 "M34551T-MCU" is printed on the board.
*4 The M34551T2-MCU has an oscillator circuit board OSC-2 (for 4.0 MHz) when shipped from
the factory. In addition, it comes with an oscillator circuit board OSC-2, with only a connector
J1 mounted.
