Notes: 1. Output buffer current is excluded.
2. Power supply current when the MCU is in the reset state and there are no I/O currents.
Test conditions: MCU:
Reset
Pins:
RESET at V_CC (V_CC – 0.3 V to V_CC)
TEST at V_CC (V_CC – 0.3 V to V_CC)

3. Power supply current when pins RD₀ and RD₁ are in analog input mode and there are no I/O
currents.
Test conditions: MCU:
DTMF not operating
Pins:
• RD₀/COMP₀: At GND (0 V to 0.3 V)
• RD₁/COMP₁: At GND (0 V to 0.3 V)
• RE₀/VC_ref: At GND (0 V to 0.3 V)
