Notes: 1. Selected with SA1 and SA0 of system control register 2 (SYSCR2).
2. The figure in parentheses applies when an external clock is used.
3. After powering on, hold VCC at 2.2 V to 5.5 V until the chip's oscillation settling time has
elapsed.
Table 16.4 Serial Interface (SCI3) Timing
V_CC = 1.8 V to 5.5 V, AV_CC = 1.8 V to 5.5 V, V_SS = AV_SS = 0.0 V, T_a = –20°C to +75°C (regular
specifications), T_a = –40°C to +85°C (wide-range specifications), T_a = +75°C (Die) (including
subactive mode) unless otherwise indicated.
