FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
1 = Current sense amplification set for measuring 0.5 A.
0 = Current sense amplification set for measuring 2.5 A.
CLS2:CLS0—H-Bridge Current Limitation Selection Bits
These read/write bits select the current limitation value
according to Table 8. Reset clears the CLS2:CLS0 bits.
Switchable VDD Outputs
The HVDD pin is a switchable VDD output pin. It can be
used for driving external circuitry that requires a VDD voltage.
The output is enabled with bit PSON in the System Control
Register and can be switched on/off with bit HVDDON in the
Power Output Register. Low or high voltage conditions (LVI/
HVI) have no influence on this circuitry.
HVDD Overtemperature Protection
Overtemperature protection is enabled if the high
temperature reset is enabled.
HVDD Overcurrent Protection
The HVDD output is protected against overcurrent. In the
event the overcurrent limit is or was reached, the output
automatically switches off and the HVDD overcurrent flag in
the System Status Register is set.
System Control Register (SYSCTL)
PSON—Power Stages On Bit
This read/write bit enables the power stages (half-bridges,
LIN transmitter and HVDD output). Reset clears the PSON
bit.
1 = Power stages enabled.
0 = Power stages disabled.
SRS0:SRS1—LIN Slew Rate Selection Bits
These read/write bits enable the user to select the
appropriate LIN slew rate for different baud rate
configurations as shown in Table 9.
The high speed slew rates are used, for example, for
programming via the LIN and are not intended for use in the
application.
Go to STOP Mode Bit (GS)
This write-only bit instructs the 908E626 to power down
and go into STOP mode. Reset or CPU interrupt requests
clear the GS bit.
1 = Power down and go into STOP mode
0 = Not in STOP mode
System Status Register (SYSSTAT)
LINCL — LIN Current Limitation Bit
This read-only bit is set if the LIN transmitter operates in
current limitation region. Due to excessive power dissipation
in the transmitter, software is advised to turn the transmitter
off immediately.
1 = Transmitter operating in current limitation region.
0 = Transmitter not operating in current limitation
region.
HVDD_OCF—HVDD Output Overcurrent Flag Bit
This read/write flag is set on an overcurrent condition at
the HVDD pin. Clear HVDD_OCF and enable the output by
writing a logic [1] to the HVDD_OCF Flag. Reset clears the
