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 47. High Side Control Register - $6
HSxCL - High Side Current Limitation
This read-only bit indicates that the high side switch is
operating in current Limitation mode.
1 = HSx in current limitation (or thermal shutdown)
0 = Normal

This register is a double purpose register which allows to
configure the watchdog and the cyclic sense periods. Writing
to the TIMCR will also return the WDSR.

PWMHSx - PWM Input Control Enable
This write-only bit enables/disables the PWMIN input pin
to control the high side switch. The high side switch must be
enabled (HSx bit).
1 = PWMIN input controls HS1 output.
0 = HSx is controlled only by SPI.

HSx - High Side Switch Control.
This write-only bit enables/disables the 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 switch and
is also returned when writing to the HSCR.
Table 48. High Side Status Register - $6/$7
CS/WD - Cyclic Sense or Watchdog Prescaler Select.
This write-only bit selects which prescaler is being written
to, the cyclic sense prescaler or the watchdog prescaler.
1 = Cyclic Sense Prescaler selected
0 = Watchdog Prescaler select
WDx - Watchdog Prescaler
This write-only bits selects the divider for the watchdog
prescaler and therefore selects the watchdog period in

High Side thermal shutdown
A thermal shutdown of the high side drivers is indicated by
setting the HSxOP and HSxCL bits simultaneously.
HSxOP - High Side Switch Open-Load Detection
This read-only bit signals that the high side switch is
conducting current below a certain threshold indicating
possible load disconnection.
1 = HSx Open Load detected (or thermal shutdown)
