Power Output Register (POUT)
CSSEL0:CSSEL1—Current Source Select Bits
This read/write bit selects the current source values. Reset
clears the
CSSEL0:CSSEL1 bits.
CSEN—Current Source Enable Bit
This read/write bit enables the current source for PA1. Reset
clears the CSEN bit (
Table 4
).
Table 4. PA1 Current Source Enable Bit
HVDDON—HVDD On Bit
This read/write bit enables HVDD output. Reset clears the
HVDDON bit.
1 = HVDD enabled.
0 = HVDD disabled.
HS_ON—Lamp Driver On Bit
This read/write bit enables the Lamp driver. Reset clears the
HS_ON bit.
1 = Lamp driver enabled.
0 = Lamp driver disabled.
Hall-Effect Sensor Input Terminals (H1:H3)
Function
The Hall-effect sensor input terminals provide three inputs
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.
Each terminal of the Hall-effect sensor can be enabled by
setting the HxEN bit in the Hall-Effect Sensor Input Terminal
Control Register (HACTL). If the terminals are enabled, the
Hall-effect sensors are supplied with V
SUP
voltage and 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).
The flag is set if the sensed current is higher than I
HSCT
.
To prevent noise on this flag, a hysteresis is implemented on
these terminals.
After switching on the Hall-effect sensor input terminals
(HxEN = 1), the Hall-effect sensors need some time to stabilize
the output. In RUN mode the software must wait at least 40
μ
s
between enabling the Hall-effect sensor and reading the
hallflag.
The Hall-effect sensor input terminal works in an dynamic
output voltage range from V
SUP
down to 2.0 V. Below 2.0 V the
hallflags are not functional anymore. If the output voltage is
below a certain threshold, the Hall-Effect Sensor Input Terminal
Overcurrent Flag (HP_OCF) in the System Status Register is
set.
Figures 11
through
13
, pp. 26–27, show the connections to
the Hall-effect input sensors.
