FUNCTIONAL DEVICE OPERATIONS
LOGIC COMMANDS AND REGISTERS
High Side Control Register - HSCR
This register controls the operation of the high side drivers.
Writing to this register returns the High Side Status Register
(HSSR).
Table 49. High Side Control Register - $6
Low Side Control Register - LSCR
This register controls the operation of the low side drivers.
Writing the Low Side Control Register (LSCR) will also return
the Low Side Status Register (LSSR).

PWMHSx - PWM Input Control Enable.
This write-only bit enables/disables the PWMIN input pin to
control the respective high side switch. The corresponding
high side switch must be enabled (HSx bit).
1 = PWMIN input controls HSx output.
0 = HSx is controlled only by SPI.
HSx - HSx Switch Control.
This write-only bit enables/disables the corresponding high
side switch.
1 = HSx switch on.
0 = HSx switch off.
High Side Status Register - HSSR
This register returns the status of the high side switches and
is also returned when writing to the HSCR.
Table 50. High Side Status Register - $6/$7
PWMLx - PWM input control enable.
This write-only bit enables/disables the PWMIN input pin to
control the respective low side switch. The corresponding low
side switch must be enabled (LSx bit).
1 = PWMIN input controls LSx.
0 = LSx is controlled only by SPI.
LSx - LSx switch control.
This write-only bit enables/disables the corresponding low
side switch.
1 = LSx switch on.
0 = LSx switch off.
Low Side Status Register - LSSR
This register returns the status of the low side switches and
is also returned when writing to the LSCR.

High Side Thermal Shutdown
A thermal shutdown of the high side drivers is indicated by
setting all HSxOP and HSxCL bits simultaneously.
HSxOP - High Side Switch Open-Load Detection
This read-only bit signals that the high side switches are
conducting current below a certain threshold indicating
possible load disconnection.
1 = HSx Open Load detected (or thermal shutdown)
0 = Normal
HSxCL - High Side Current Limitation
This read-only bit indicates that the respective high side
switch is operating in current limitation mode.
1 = HSx in current limitation (or thermal shutdown)
0 = Normal
Low Side Thermal Shutdown
A thermal shutdown of the low side drivers is indicated by
setting all LSxOP and LSxCL bits simultaneously.
LSxOP - Low Side Switch Open-Load Detection
This read-only bit signals that the low side switches are
conducting current below a certain threshold indicating
possible load disconnection.
1 = LSx Open Load detected (or thermal shutdown)
0 = Normal
LSxCL - Low Side Current Limitation
This read-only bit indicates that the respective low side switch
is operating in current limitation mode.
1 = LSx in current limitation (or thermal shutdown)
0 = Normal
