FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
Hall-Effect Sensor Input Pin H0
The H0 pin can be configured as general purpose input
(H0MS = 0), or as hall-effect sensor input (H0MS = 1), to be
able to read 3-pin / 2-pin hall sensors or switches.
Figure 18. General Purpose / Hall-effect Sensor Input (H0)
Current Coded Hall sensor Input
H0 is selected as “2-pin Hall sensor input”, if the
corresponding H0MS bit in the H0/L0 Status and Control
Register (HLSCTL) is set. In this mode, the pin current to
GND is monitored by a special sense circuitry. Setting the
H0EN bit in the H0/L0 Status and Control Register, switches
the output to VSUP and enables the sense circuitry. The
result of the sense operation is given by the H0F flag. The
flag is low if the sensed current is higher than the sense
current threshold IHSCT. In this configuration, the HO pin is
protected (current limitation) against a short circuit to GND.
After switching on the hallport (H0EN = “1”), the Hall
sensor needs some time to stabilize the output. In RUN
mode, the software has to take care about waiting for a few
s (40) before sensing the hallflags.
The hallport output current is sensed. In case of an over-
current (short to GND), the hallport over-current flag
(H0OCF) is set and the current is limited. For proper
operation of the current limitation, an external capacitor
(>100 nF) close to the H0 pin is required.
