FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
OPERATING MODES OF THE MCU
For a detailed description of the operating modes of the
MCU, refer to the MC68HC908EY16 datasheet.
INTERRUPTS
The 908E621 has seven different interrupt sources. An
interrupt pulse on the IRQ_A pin is generated to report an
event or fault to the MCU. All interrupts are maskable and can
be enabled/disabled via the SPI (Interrupt Mask Register).
After reset, all interrupts are automatically disabled.
Low Voltage Interrupt
Low voltage interrupt (LVI) is related to external supply
voltage VSUP. If this voltage falls below the LVI threshold, it
will set the LVIF bit in the Interrupt Flag Register. If the low
voltage interrupt is enabled (LVIE = 1), an interrupt will be
initiated.
During Sleep and Stop mode, the low voltage interrupt
circuitry is disabled.
High Voltage Interrupt
The High voltage Interrupt (HVI) is related to the external
supply voltage VSUP. If this voltage rises above the HVI
threshold, it will set the HVIF bit in the Interrupt Flag Register.
If the High voltage Interrupt is enabled (HVIE = 1), an
interrupt will be initiated.
During Stop and Sleep 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 HTIF bit in the Interrupt Flag Register
will be set. If the high temperature interrupt is enabled (HTIE
= 1), an interrupt will be initiated.
During Stop and Sleep mode, the HTI circuitry is disabled.
LIN Interrupt
The LIN Interrupt is related to the Stop mode. If the LIN
interrupt is enabled (LINIE = 1) in Stop mode, an interrupt is
asserted if a rising edge is detected, and the bus was
dominant longer than TPROPWL. After the wake-up / interrupt,
the LINIF indicates the reason for the wake-up / interrupt.
Power Stage Fail Interrupt
The power stage fail flag indicates an error condition on
power stage fail interrupt is enabled (PSFIE = 1), an interrupt
will be initiated if:
During Stop and Sleep mode, the PSFI circuitry is
disabled.
HO Input Interrupt
The H0 interrupt flag H0IF is set in run mode by a state
change of the H0F flag (rising or falling edge on the enabled
input). The interrupt function is available if the input is
selected as General Purpose, or as a 2-pin Hall sensor input.
The interrupt is maskable with the H0IE bit in the Interrupt
Mask Register.
During Stop and Sleep mode, the H0I circuitry is disabled.

Notes
35.
The SPI is still active in Stop mode. However, due to the limited current capability of the voltage regulator in Stop mode, the PSON bit
has to be set before the increased current caused from a running MCU causes an LVR.
