5.1.6

Voltage Detector and Power Supply Circuit Electrical Characteristics

Notes:

Select the voltage detection level with the VDSEL1 bit in the OFS1 address.

Necessary time until the voltage detector operates when setting to 1 again after setting the VC25 bit in the VCR2

Time from when passing the Vdet0 until when a voltage monitor 0 reset is generated.

Notes:

Select the voltage detection level with bits VD1S0 to VD1S3 in the VD1LS register.

Necessary time until the voltage detector operates when setting to 1 again after setting the VC26 bit in the VCR2

Time from when passing the Vdet1 until when a voltage monitor 1 reset is generated.

Table 5.12

Voltage Detector 0 Electrical Characteristics

The measurement condition is VCC1 = 1.8 to 5.5 V, Topr = -20 to 85°C/-40 to 85°C, unless otherwise
