60 / 89 page  5. Electrical Characteristics REJ03B0243-0030 Rev.0.30 Jan 21, 2009 Page 58 of 76 R8C/L35A Group, R8C/L36A Group, R8C/L38A Group, R8C/L3AA Group, R8C/L35B Group, R8C/L36B Group, R8C/L38B Group, R8C/L3AB Group Under development Preliminary specification Specifications in this manual are tentative and subject to change. Notes: 1. This indicates the precision error for the oscillation frequency of the high-speed on-chip oscillator. 2. This enables the setting errors of bit rates such as 9600 bps and 38400 bps to be 0% when the serial interface is used in UART mode. Note: 1. Waiting time until the internal power supply generation circuit stabilizes during power-on.
