Notes: 1. Output buffer current is excluded.
2. I_CC1 is the source current when no I/O current is flowing while the MCU is in reset state.
Test conditions:
MCU: Reset
Pins: RESET, TEST, D₀–D₇, D₉, D₁₀, R0–R5 at V_CC
D₈ open
3. I_SBY is the source current when no I/O current is flowing while the MCU timer is in operation.
Test conditions:
MCU: I/O reset
Serial interface stopped
Standby mode
Pins: RESET at GND
TEST, D₀–D₇, D₉, D₁₀, R0–R5 at V_CC
D₈ open
4. D₁₀ is connected to V_CC in the HD4074329 and HD4074329U.
5. RAM data retention.
