Bit Description
ECMOCIF ⁽²⁾: Over-current interrupt flag of the ECM driver.
0 1 = Over-current event has been detected at the ECM output, and the driver has been disabled.
0 = There is no over-current at ECM output.
1) To keep current consumption as low as possible, the MCU software should disable the current sources before enabling SLEEP or STANDBY Modes.
2) This bit is also mapped to IRQSTAT register.

1) Important: The diagnostic result is correct only if the driver is disabled.
2) In the event of a short to VSS, the output stage of the driver will be automatically disabled if the current exceeds the threshold specified in Table 1.9. If
the current is limited to levels below that threshold due to specifics of the EC mirror glass used, distinguishing between the two possible states, which
are “Normal load” or “Short to VSS,” can be done by an additional ADC channel and software procedure for measuring the potential at EC_M pin (for
more details, see section 3.11.1).
3.12. ZAMC4100 Analog to Digital Converter
The ZAMC4100 features a 10-bit successive approximation ADC with a front-end multiplexer for digitizing the
multi-channel inputs, including four external ports.
3.12.1. ADC Overview
The ZAMC4100 ADC block has the following key features:
• SAR (successive approximation) conversion, 10-bit resolution, single or continuous conversion
• High conversion speed (see Table 1.15)
• Multi-channel front-end multiplexer with access to various input signals as shown in the Figure 3.20;
4 external channel ports with versatile options
• Internal voltage and current references
• Configurable result format
• Result comparator with counter
• Interrupt support for various type of events
