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
PSON bit in the System Control Register.

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 hall flag.
