FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
Figure 21. H0 Used to Read in Standard Switches
H0 Interrupt
The interrupt functionality on this pin is only available in
RUN mode. H0 interrupt flag H0IF is set in run mode by a
state change of the H0 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 can be masked with the H0IE bit in the
interrupt mask register.
Wake-up Input L0
The device provides one wake-up capable input for
reading VSUP or VDD related signals.
RUN Mode
The actual input state is reflected in the L0F bit of the H0/
L0 Status and Control register (HLSCTL).
The L0 pin offers an interrupt capability on rising and
falling edge. The interrupt can be enabled with the L0IE bit in
the Interrupt Mask register.
STOP/SLEEP Mode
During STOP and SLEEP mode, the pin can be used to
wake-up the device.
Before entering the STOP or SLEEP mode, the actual
state of the input is stored. If the state is changing during in
the STOP or SLEEP mode, a wake-up is initiated.
H0 / L0 Status and Control Register (HLSCTL)
L0F — L0 Flag Bit
This read only flag reflects the state of the L0 input
1 = L0 input high
0 = L0 input low
H0OCF — H0 Over-current Flag Bit
This read/write flag is set with an over-current condition on
H0 during 2pin Hall sensor mode. Clear H0OCF by writing a
logic [1] to H0OCF. Reset clears the H0OCF bit.
1 = over-current condition on H0 pin has occurred
0 = no over-current condition on H0 pin has occurred
H0F — H0 Flag Bit
This read only flag reflects the state of the H0 input
1 = Hallport sensed high / current below threshold
detected
0 = Hallport sensed low / current above threshold
