Analog-to-Digital Converter (ADC)
MC68HC908JL16 Data Sheet, Rev. 1.1
130
Freescale Semiconductor
If ACLKEN is set, a conversion can be initiated while in stop using the external hardware trigger
ADEXTCO when in external convert mode. The ADC10 will operate in a low-power mode until the trigger
is asserted, at which point it will perform a conversion and assert the interrupt when complete (if AIEN is
set).
9.6 ADC10 During Break Interrupts
The system integration module (SIM) controls whether status bits in other modules can be cleared during
the break state. BCFE in the break flag control register (BFCR) enables software to clear status bits during
the break state. See BFCR in the SIM section of this data sheet.
To allow software to clear status bits during a break interrupt, write a 1 to BCFE. If a status bit is cleared
during the break state, it remains cleared when the MCU exits the break state.
To protect status bits during the break state, write a 0 to BCFE. With BCFE cleared (its default state),
software can read and write registers during the break state without affecting status bits. Some status bits
have a two-step read/write clearing procedure. If software does the first step on such a bit before the
break, the bit cannot change during the break state as long as BCFE is cleared. After the break, doing the
second step clears the status bit.
9.7 Input/Output Signals
The ADC10 module shares its pins with general-purpose input/output (I/O) port pins. The ADC10 on this
MCU uses VDD and VSS as its supply and reference pins. This MCU does not have an external trigger
source.
9.7.1 ADC10 Analog Power Pin (VDDA)
The ADC10 analog portion uses VDDA as its power pin. In some packages, VDDA is connected internally
to VDD. If externally available, connect the VDDA pin to the same voltage potential as VDD. External filtering
may be necessary to ensure clean VDDA for good results.
NOTE
If externally available, route VDDA carefully for maximum noise immunity
and place bypass capacitors as near as possible to the package.
9.7.2 ADC10 Analog Ground Pin (VSSA)
The ADC10 analog portion uses VSSA as its ground pin. In some packages, VSSA is connected internally
to VSS. If externally available, connect the VSSA pin to the same voltage potential as VSS.
In cases where separate power supplies are used for analog and digital power, the ground connection
between these supplies should be at the VSSA pin. This should be the only ground connection between
these supplies if possible. The VSSA pin makes a good single point ground location.
9.7.3 ADC10 Voltage Reference High Pin (VREFH)
VREFH is the power supply for setting the high-reference voltage for the converter. In some packages,
VREFH is connected internally to VDDA. If externally available, VREFH may be connected to the same
potential as VDDA, or may be driven by an external source that is between the minimum VDDA spec and
the VDDA potential (VREFH must never exceed VDDA).
