47 / 92 page ![]() R01DS0032EJ0200 Rev.2.00 Page 47 of 88 Feb 07, 2011 M16C/64A Group 5. Electrical Characteristics 5.1.6 Voltage Detector and Power Supply Circuit Electrical Characteristics Notes: 1. Select the voltage detection level with the VDSEL1 bit in the OFS1 address. 2. Necessary time until the voltage detector operates when setting to 1 again after setting the VC25 bit in the VCR2 register to 0. 3. Time from when passing the Vdet0 until when a voltage monitor 0 reset is generated. Notes: 1. Select the voltage detection level with bits VD1S0 to VD1S3 in the VD1LS register. 2. Necessary time until the voltage detector operates when setting to 1 again after setting the VC26 bit in the VCR2 register to 0. 3. Time from when passing the Vdet1 until when a voltage monitor 1 reset is generated. Table 5.11 Voltage Detector 0 Electrical Characteristics The measurement condition is VCC1 = 2.7 to 5.5 V, Topr = -20°C to 85°C/-40°C to 85°C, unless otherwise specified.
