NOTES:
1. Referenced to VCC= 4.2 to 5.5 V, VSS= 0 V at Topr = -20 to 85° C / -40 to 85 ° C, f(BCLK) = 20 MHz unless otherwise
specified.
2. With one timer operates, using fC32.
3. This indicates the memory in which the program to be executed exists.
4. Idet is dissipation current when the following bit is set to "1" (detection circuit enabled).
Idet4: VC27 bit in the VCR2 register
Idet3: VC26 bit in the VCR2 register
