Notes: 1. Output buffer current is excluded.
2. ICC 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 at VCC
3. ISBY is the source current when no I/O current is flowing while the MCU timer is in operation.
Test conditions:
D12, D13 in digital input mode
DTMF in operation (excludes current flowing from VTref to GND)
4. Pins D12 and D13 are in analog input mode and I/O current is not flowing.
Test conditions:
VCref/D11, COMP0/D12, COMP1/D13 at GND
DTMF stopped
5. Timer is in operation and I/O current is not flowing.
Test conditions:
MCU: I/O in reset state
Serial interface stopped
D12, D13 in digital input mode
DTMF stopped
Stanby mode
Pins : RESET at GND
TEST at VCC
6. Applies only to HD404612, HD404614, HD404616, and HD404618.
7. RAM data retention.
