ADC Reference Terminals (VREFL and VREFH)
VREFL and VREFH are the reference voltage terminals for
the ADC. It is recommended that a high-quality ceramic
decoupling capacitor be placed between these terminals.
Important
VREFH is the high reference supply for the ADC
and should be tied to the same potential as VDDA via separate
traces. VREFL is the low reference supply for the ADC and
should be tied to the same potential as VSS via separate traces.
For details refer to the 68HC908EY16 datasheet.
ADC Supply Terminals (VDDA and VSSA)
VDDA and VSSA
are the power supply terminals for the
analog-to-digital converter (ADC). It is recommended that a
high-quality ceramic decoupling capacitor be placed between
these terminals.
Important
VDDA is the supply for the ADC and should be
tied to the same potential as EVDD via separate traces. VSSA
is the ground terminal for the ADC and should be tied to the
same potential as EVSS via separate traces.
For details refer to the 68HC908EY16 datasheet.
MCU Power Supply Terminals (EVDD and EVSS)
EVDD
and EVSS
are the power supply and ground
terminals. The MCU operates from a single power supply.
Fast signal transitions on MCU terminals place high, short-
duration current demands on the power supply. To prevent
noise problems, take special care to provide power supply
bypassing at the MCU.
For details refer to the 68HC908EY16 datasheet.
Test Terminal (FLSVPP)
For test purposes only. Do not connect in the application.
Exposed Pad Terminal
The exposed pad terminal on the bottom side of the package
conduct
s
heat from the chip to the PCB board. For thermal
performance the pad must be soldered to the PCB board. It is
recommended that the pad be connected to the ground
potential.
ANALOG DIE DESCRIPTION
Interrupts
The 908E625 has seven different interrupt sources as
described in the following paragraphs. The interrupts can be
disabled or enabled via the SPI. After reset all interrupts are
automatically disabled.
Low-Voltage Interrupt
The Low-Voltage Interrupt (LVI) is related to the external
supply voltage, V
SUP
. If this voltage falls below the LVI
threshold, it will set the LVI flag. If the low-voltage interrupt is
enabled, an interrupt will be initiated.
With LVI the H-Bridges (high-side MOSFET only) and the
high-side driver are switched off. All other modules are not
influenced by this interrupt.
During STOP mode the LVI circuitry is disabled.
High-Voltage Interrupt
The High-Voltage Interrupt (HVI) is related to the external
supply voltage, V
SUP
. If this voltage rises above the HVI
threshold, it will set the HVI flag. If the High-Voltage Interrupt is
enabled, an interrupt will be initiated.
With HVI the H-Bridges (high-side MOSFET only) and the
high-side driver are switched off. All other modules are not
influenced by this interrupt.
During STOP mode the HVI circuitry is disabled.
High-Temperature Interrupt
The High-Temperature Interrupt (HTI) is generated by the
on-chip temperature sensors. If the chip temperature is above
the HTI threshold, the HTI flag will be set. If the High-
Temperature Interrupt is enabled, an interrupt will be initiated.
During STOP mode the HTI circuitry is disabled.
Autonomous Watchdog Interrupt (AWD
)
Refer to Autonomous Watchdog (AWD) on page 36.
LIN Interrupt
If the LINIE bit is set, a falling edge on the LIN terminal will
generate an interrupt. During STOP mode this interrupt will
initiate a system wake-up.
Hall-Effect Sensor Input Terminal Interrupt
If the PHIE bit is set, the enabled Hall-effect sensor input
terminals H1:H3 can generate an interrupt if a current above
the threshold is detected. During STOP mode this interrupt,
combined with the cyclic wake-up feature of the AWD, can
wake up the system (refer to
Hall-Effect Sensor Input Terminals
(H1:H3) on page 25
).
Overcurrent Interrupt
If an overcurrent condition on a half-bridge occurs, the high-
side or the HVDD output is detected and the OCIE bit is set and
an interrupt generated.
