36 / 54 page  R8C/33G Group, R8C/33H Group 5. Electrical Characteristics Under development Preliminary document Specifications in this document are tentative and subject to change. REJ03B0306-0010 Rev.0.10 Page 36 of 51 Jul. 21, 2010 Notes: 1. The measurement condition is VCC = 2.7 V to 5.5 V and Topr = −40 to 85°C (J version) / −40 to 125°C (K version). 2. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA25 bit in the VCA2 register to 0. 3. Time until the voltage monitor 0 reset is generated after the voltage passes Vdet0. Notes: 1. The measurement condition is VCC = 2.7 V to 5.5 V and Topr = −40 to 85°C (J version) / −40 to 125°C (K version). 2. Select the voltage detection level with bits VD1S0 to VD1S3 in the VD1LS register. 3. Time until the voltage monitor 1 interrupt request is generated after the voltage passes Vdet1. 4. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2 register to 0.
