Hall-Effect Sensor Input Terminals (H1:H3)

for two-terminal Hall-effect sensors for detecting stall and
position or reading Hall-effect sensor contact switches. The
Hall-effect sensor input terminals are not influenced by the

sense circuitry is working. An internal clamp circuity limits the
supply voltage to the sensor to 15 V. This sense circuitry
monitors the current to VSS. The result of this sense operation
is given by the HxF flags in the Hall-Effect Sensor Input
Terminal Status Register (HASTAT).
To prevent noise on this flag, a hysteresis is implemented on
these terminals.
(HxEN = 1), the Hall-effect sensors need some time to stabilize
the output. In RUN mode the software must wait at least 40 µs
between enabling the Hall-effect sensor and reading the
hallflag.
