Data based on characterization results, not tested in production.

CPU running with memory access, all I/O pins in input mode with a static value at VDD or VSS (no load), all peripherals in

reset state; CPU clock provided by the internal RC, LVD disabled.

All I/O pins in input mode with a static value at VDD or VSS (no load), all peripherals in reset state; CPU clock provided by

the internal RC, LVD disabled.

Slow mode selected with fCPU based on fOSC divided by 32. All I/O pins in input mode with a static value at VDD or VSS (no

load), all peripherals in reset state; CPU clock provided by the internal RC, LVD disabled.

Slow-Wait mode selected with fCPU based on fOSC divided by 32. All I/O pins in input mode with a static value at VDD or VSS

(no load), all peripherals in reset state; CPU clock provided by the internal RC, LVD disabled.
