*1 The main clock oscillation stabilization time is generated by dividing the main clock oscillation. Since
the oscillation cycle is unstable immediately after oscillation starts, the time in this table is only a guide.
*2 Port/segment output switching should be specified in the same manner as the port allocation set by
the segment output select register in the LCD controller described on page 2-61.
*3 When those pins are used as ports, applied voltage should never be higher than V3.
