Figure 18. General Purpose / Hall-effect Sensor Input (H0)
Current Coded Hallsensor 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
(>100nF) close to the H0 pin is required.
